ICS Part 1 Physics English Medium Chapter 2 Online Short Questions Test with Answers

Question # 1

Give two conditions of equilibrium.

Ans 1:

Question # 2

Differentiate between static and dynamic equilibrium.

Ans 1: Static Equilibrium: If a body is at rest, then it is said to be in static equilibrium.
Dynamic Equilibrium: If the body is moving with uniform velocity, then it is said to be in dynamic equilibrium.

Question # 3

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.

Question # 4

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.

Question # 5

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 # 6

Define unit vector.How we find it?

Ans 1: A unit vector in a given direction is a vector with magnitudes one in that direction.Its is used to represent the direction of a vector.

Question # 7

The resultant of two vector, one is double in magnitude than the other, perpendicular to the smaller force. What is the angle between the two forces ?

Ans 1:

Question # 8

What are rectangular components of a vector?

Ans 1: The components of a vector which are perpendicular to each are called rectangular components.

Question # 9

Explain rectangular coordinates system.

Ans 1: Two lines drawn at right angles to each other are know as coordinate axes and their point of intersection is known as origin. This system of coordinate axes is called rectangular coordinate system.
The horizontal line is named x-axis and vertical line y-axis.The direction of x-axis is positive towards right and y-axis is positive upward.

Question # 10

Define unit vector?

Ans 1: A vector whose magnitude is one is known as unit vector
