Two wooden blocks of masses M and m are placed on a smooth horizontal surface as shown in figure. If a force P is applied to the system as shown in figure such that the mass m remains stationary with respect to block of mass M , then the magnitude of the force P is
Options
- A(M+m) g
- Bg
- Cm g
- D(M+m) g cosec
Correct answer
A. (M+m) g
Step-by-step solution
The free body diagram of the given situation is aligned & Force = Mass Acceleration & P=(M+m) a & m a =m g & a=g & =g & P=(M+m) g & aligned
