m2 and M are 20 kg

Sahay Sir > Question Answers > m2 and M are 20 kg
In the figure , masses m1 , m2 and M are 20 kg , 5 kg and 50 kg respectively . The coefficient of friction between M and ground is zero . The coefficient of friction between m1 and M and that between m and ground 0.4 . The pulleys and the string are massless . The string is perfectly horizontal between P1 and m1 and also between P1 and m2 . The string is perfectly vertical between P1 and P2 . An external horizonatal force F is applied to the mass M . Take g = 10 m /s^2
