Question

please help me over it

Answer 1

Hey

-> Eh! No option for theta.. I'm using 'x' for theta

--> T(Q) = vg
=> T(M.Q) = T(Q) cos x

Similarly, T(M.P) = T(P)cos x

Since, mass(P) = mass(Q) ✓✓
--> T(M.Q) applies in the same direction as T(M.P)

=> Resultant T(M) = 2 T(P) cos x
=> Mass M moves up with a speed of 2v cos x

^_^ Hope this helps ✓✓
