### What is the effect of the change in the radius of revolution to the period of revolution?

period of revolution = T
T = 2. pi. r / w
...............where r is radius and w is angular velocity
as v = w.r..................................(v is linear
velocity).
w = v/r
T = 2.pi.r / (v/r)
T = 2.pi.r^2/v
r^2 = T.v / 2.pi
so r is proportional to square root of T
so if r is increased by 'n' times, T increases by sqrt(n)
times.
