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

Question # 1

Discuss the commutative property of addition of vectors ?

Ans 1:

Question # 2

Why can a vector not have a component greater than the vectors magnitude?

Ans 1: The magnitude of the components of a vector can not be greater than the vectors magnitude because component is always a part of the resultant vector. This relation show that if any two components of a vector are zero then the magnitude of the third components may be equal to the vectors magnitude but it can never be greater.

Question # 3

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 # 4

Define position vector and resultant vector.

Ans 1: Position Vector: A vector which describes the location of a point with respect to origin is called position vector.

Resultant Vector: A Single vector which would have the same effect as all the original vectors taken together.

Question # 5

What is the moment of a force about the point lying on the axis of rotation?

Ans 1:

Question # 6

Two vectors have unequal magnitude.Can their components be equal in magnitude?

Ans 1: No, the components of two vectors cannot be equal in magnitude if the two vector have unequal magnitudes.

Question # 7

Write down the condition for a body to be in complete equilibrium.

Ans 1:

Question # 8

Can you add zero to a null vector?

Ans 1: No, zero can't be added to a null vector because zero is a scalar and scalars can't be added to vectors Only the physical quantities of same nature can be added.

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

The vector sums of three vectors give a null vector. What can be orientation of the vectors?

Ans 1: If the three vectors are oriented in cyclic order i.e in the form of triangle, then they will give rise to null vector.
