Solution

## The correct option is C The acceleration of the body after L is zero.In the given velocity-time plot of a body: The slope of the segment OK is increasing, thus, the body's velocity is increasing with time till K, i.e. the acceleration of the body is also increasing, and is positive. The slope of the segment KL is decreasing, thus, the body's velocity is decreasing with time till L, i.e. the acceleration of the body is also decreasing, and is negative. After L, the slope becomes constant, i.e. the body's velocity does not change with time. So, the acceleration after L is zero.
