Hint: there are two componnents of acceleration..
One towards the center another tangentially..
The vector sum will give the resultant acceleration.
Hence find the force.
simple sum v^2=4as/m here v is speed and s is the distance and tangential force is dv/dt where v is speed P.S. i wrote this as i always get confused between speed and vel
At the instant after the system of objects is released, find the accelerations o . ... about an axis passing through its centre and perpendicular to its symmetry axis. ... In the fig. shown a smooth ring is connected to rod AB while rod CD passes thru ring . At the given instant angular vel. of rod AB abt hinge A is 1 rad/s and AC=CB.
