Physics - ICS Part 1 Physics Chapter 2 Short Questions Test

Question # 1

Discuss the addition of vector by rectangular component method?

Ans 1:

Question # 2

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 # 3

What are rectangular components of a vector?

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

Question # 4

Discuss the multiplication of a vector by a number?

Ans 1: We can multiple a vector by a number. If the number is positive, then the direction of given vector and product vector will remain the same. If the number id negative, then the given vector and product vector will be acting in opposite direction.

Question # 5

Define and explain the scalar product?

Ans 1:

Question # 6

Define unit vector?

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

Question # 7

How would the two vectors of the same magnitudes have to be oriented,if they were to be combined to give a vector of the same magnitude?

Ans 1: The two vectors of equal magnitudes are combined to give a resultant vector of same magnitude when must be oriented at an angle of 120⁰ With each other.

Question # 8

Define and explain the resolution of a vector ?

Ans 1:

Question # 9

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

Ans 1:

Question # 10

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.
