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.

    Question # 1

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

    • 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 addition of vectors by graphical Method or geometrical Method?

    • Ans 1: We can add two or more than two vectors by geometrical method or graphical method to get their resultant vector. we use "Head-to-Tail rule for addition of vectors by graphical method or geometrical method.
      The following steps must be followed to add vectors buy head-to-tail rule:
      1. Select a suitable scale for the representation of given vectors
      2. Draw the 1st vector according to the selected scale in the given direction
      3. Draw the second vector according to the selected scale in the specified direction such that its tail touches the head of the first vector.
      4. Now draw the 3rd vector according to the selected scale in the specified direction such that its tail touches the head of the second vector
      5. Continue the above process for given number of vectors.
      6. For getting the resultant vector, combination the tail of the first vector.
      7. Measure the length of R which will given its magnitude.
      8. To determine the direction of R measure the angle of R with respect to positive X-direction in anti clock wise sense.
