In Fig.7.125, coefficient of friction between `m_(1)` and `m_(2)` is `mu` and that between `m_(1)` and the wall is zero. A force F is pressing the system against the wall. Minimum value of force required to hold the system in equilibrium is :

In Fig. 7.150 , coefficient of friction between m_(2) and the horizontal surface is mu , minimum value of m so that the system has zero acceleration , is :

If system is in equilibrium then find relation between m_(1) and m_(2)

If system is in equilibrium then find relation between m_(1) and m_(2)

If system is in equilibrium then find relation between m_(1) and m_(2)

In the figure, a ladder of mass m is shown leaning against a wall. It is in static equilibrium making an angle theta with the horizontal floor. The coefficient of friction between the wall and the ladder is mu_1 and that between the floor and the ladder is mu_2. the normal reaction of the wall on the ladder is N_1 and that of the floor is N_2. if the ladder is about to slip. than
