Solution

The correct option is D The magnitude of acceleration is constant in (a) and increasing in (b)
By observing both the figure we see that in fig (A) radius will remain constant while in fig (B) radius will vary as the particle complete one circumference.
a=v2/r
Given v is constant and r reduces in spiral path. Hence, a increases in spiral path.
