Acceleration of the particle is positive.

Options

A. In graph (i)
B. In graph (ii)
C. In graph (iii)
D. In graph (iv)

Answer

c

Explanation

In graph (iii), magnitude of slope of gragh is dereasing. Hence, magnitude of velocity is dereasing but in negative direction, hence acceleation is positive.
