Acceleration of a particle varies as a = v^2, where v is the velocity of particle. If initially the particle was at rest, then?

A) particle starts moving with non-uniform acceleration.
B) particle does not starts moving.
C) particle starts moving with uniform acceleration.
D) none of these.
The answer is C for your reference. ( however it may be wrong)!

The acceleration is a = v^2

However initially, v = 0 and therefore, a=0 and hence the particle doesn't start moving at all.

Unless you supply the particle with some initial velocity, it can have no acceleration and hence it doesn't move at all.
