Suppose the acceleration of a particle moving with uniform speed 'V' in a circle of radius 'r' is proportional to some power of 'r', say, r and some power of 'V

Suppose the acceleration of a particle moving with uniform speed 'V' in a circle of radius 'r' is proportional to some power of 'r', say, r" and some power of 'V', say's'
Determine the values of 'n' and 'm' and
write the simplest form of an equation for
the acceleration.
