Homework Statement
A point object of mass m is connected to an inertialess string of length L, the other end of which is connected to a fixed point O. At time t=0, the object is assumed to move horizontally in a vertical plane from the bottom point A (OA=L). in the clockwise direction with...
so,
P1 = p + Mg/S ... (1)
P2 + Mg/S = p
or, P1 + 2Mg/S = 2p ... (2) (since, P2 = P1/2)
subtracting (1) from (2)
2Mg/s = p - Mg/s
or, p = 3Mg/s
So, the correct answer is option (a).
Thanks for your help.
