First Year Physics Chapter 2 Online Short Questions Preparation for 1st Year Physics Chapter 2 (Vectors and Equilibrium)

Science is all around us, in everything we have a tendency to do. It's the building block for everything in our daily lives, as well as mobile devices, design (ancient and modern), art, money, engineering, and even sports.

Start reading ilmkidunya.com’s short queries with answers. Effective learning will never be done through cramming the definitions and topics. You have got to grasp the idea. After you perceive the idea of the subject, it doesn't matter with which manner the question is being asked in Boards examinations, you'll be ready to answer it accurately. Understanding is the key issue to realize success.ilmkidunya.com tends to wholly advocate scan your book to earn information instead of cramming your information. The short questions at our website ilmkidunya.com can check your understanding and learning.

By taking this online session of chapter 2 students will be able to understand the concepts:

  • Understand and use rectangular coordinate system

  • To understand and define the idea of unit, null, and position vector

  • Represent a vector as two perpendicular components

  • To define and Understand the rule of addition of vectors and extend it to add vectors using rectangular components

  • Understand multiplication of vectors and solve problems

  • Define the moment of force or torque

  • understanding the use of the torque due to force

  • Show an understanding that a system is in equilibrium when there is no resultant force and torque,

  • Appreciating and defining the application of the principle of moments

  • Apply the knowledge gained to solve problems on statistics

    • This online preparation method is very easy for the students of 11th class and any student will use it once logged in. It’s very easy to try to and also very helpful for exams preparations. Also try out our past papers, check your results, date sheets, get the notes, attend the online lecture sessions any many more at ilmkidunya.com which will be beneficial for all types of students

    Question # 1

    What is the minimum number of unequal vector in to a null vector?

    • Ans 1: The minimum number of unequal vector to result in to a null vector must be three. If we add three vector of unequal magnitude in such a way that they forms the sides of a triangle, then their resultant must be zero.
      In the given figure three vectors A, B, and C are added according to head to tail rule and they form the side of a triangle. Now for getting their resultant, we will combine the tail of A with the head of C which already coincides each other. Thus we get a null vector or zero vector as a resultant
      R= A+B+C = 0

    Question # 1

    Discuss the condition of equilibrium?

    • Ans 1: There are two condition of equilibrium which are given below.First Condition of equilibrium:According to the first condition of equilibrium, a body is said to be in equilibrium, if the vector sum of all external forces acting on the body is zero they cancel the effect of each other { F = 0In the component form we haveF1y+ F2y + F3y +................ +Fny =0Fy = 0A book lying on the table and paratrooper moving down words with uniform Velocity satisfies the first condition of equilibrium.Second Condition of Equilibrium:According to the condition of equilibrium, a body is said to be in equilibrium on a body is equal to zero.{ T = 0Explanation:There are certain situation in which on extended body will not be in equilibrium even when the first condition of equilibrium is satisfied. For Example, in the two equal forces are acting on a meter rod in opposite direction. As the line of action of these forces are not the same so the meter rod do not remain in state equilibrium and begins to rotate in anti clock wise direction. So the first condition of equilibrium is not sufficient in such a case Under such situations we should arrange the forces on the body in such a way, htat they causes clock-wise torque and anti-clock wise torque acting on the body simultaneously and cancel the effect other.

    Question # 1

    What do you mean by concurrent force ? Explain with examples ?

    • Ans 1: Concurrent Force:Two or more than two force are said to be concurrent force, If they are acting upon a body and their lines of action passes through a common point.Explanation:Consider a bulb which is suspended by means of a thread from a rigid support In this case the weight 'w' of the bulb is acting in down wards direction while the tension 'T' in the thread is acting of both forces passes through the same point or common point. Both forces balance each other and as a a result the bulb remain the state of equilibrium such force are know as concurrent forces.
