Two wooden blocks are moving on a smooth horizontal surface such that the mass 'm' remains stationary with respect to block of mass M as shown in figure. The magnitude of force P is –
A
(M + m)g tan b
B
g tan b
C
mgcosb
D
(M + m) g cosec b
Answer
(M + m)g tan b
Explanation
Solution
As we have discussed in class room, acceleration required to stop the incline plane is
a = g tan
Total force to move the system,
P = (M + m)a
= (M + m) g tan
