Question (1)

QN0034733

The location of a particle has changed. What can we say about the displacement and the distance covered by the particle?

(A)
Neither can be zero
(B)
One may be zero
(C)
Both may be zero
(D)
One is +ve, other is -ve

Correct Answer: A

Explanation:

When location of a particle has changed, it must have covered some distance and undergone some displacement.

QN0034738

An athlete completes one round of a circular track of radius in . What will be his displacement at the end of ?

(A)
Zero
(B)
(C)
(D)

Correct Answer: A

Explanation:

(a) Total time of motion is .

As time period of circular motion is so in athlete will complete 5 revolution i.e., he will be at starting point i.e., displacemet zero.
