MCQ
The adjoining diagram shows the velocity versus time plot for a particle. The work done by the force on the particle is positive from
- ✓$A$ to $B$
- B$B$ to $C$
- C$C$ to $D$
- D$D$ to $E$
✓
Answer
Correct option: A.
$A$ to $B$
(a) From the graph it is clear that force is acting on the particle in the region $A B$ and due to this force kinetic energy (velocity) of the particle increases.Sotheworkdonebytheforce is positive.
