Expert Solution
Step 1
Here m1 rotates in a circle of r radius.
Let the velocity of the mass m1 be v.
Mathematically, centripetal acceleration of mass m1 is given by,
ac = m1v2/r
Here during rotation of mass m1 and produce centripetal acceleration and this acceleration is balanced by the weight of hanging mass m2
Weight of mass m2 is given by = m2g
