by the force upto time `t(let_(0)).`

A

First decreases then increases

B

First increases then decreases

C

Always increases

D

Always decreases

Text Solution

Verified by Experts

The correct Answer is:
C
The work done by force from time `t=0` to `t=tsec.` is given by shaded area in graphs below. Hence as `t` increases, this area increses.

`:. `Work done by force keeps on increasing .
