Assertion: `x-t` graph, for a particle undergoing rectilinear motion, can be as shown in the figure.
Reason: Infinitesimal changes in velocity are physically possible only in infinitesimal time.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assersion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
At the high point of the graph velocity (slope of `x-t` curve) charges suddenly from a positive to a negative value. This is physically impossible.
