Question

Two particle having masses M and m are moving in a circular path having radius R and r respectvely.If their periods are same,then the ratio of th angular velocities will be-----
a)R/r
b)(R/r)^0.5
c)r/R
d)1

Answer 1

The two particles m and M are moving in a circular motion with different radii  r and R..

   Time period = T = 2 π / ω
        =>      T1/ T2 =  ω2 / ω1
       =>    ω2 / ω1 = 1  as  T1 = T2
