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

Options

A. `mu_(1) = 0 mu_(2) ne 0 and N_(2) tan theta = (mg)/(2)`
B. `mu_(1) ne 0 mu_(2) = 0 and N_(1) tan theta = (mg)/(2)`
C. `mu_(1) ne 0 mu_(2) ne 0 and N_(2) = (mg)/(1 + mu_(1) mu_(2)) `
D. `mu_(1) = 0 mu_(2) ne 0 and N_(1) tan theta = (mg)/(2)`

Answer

C, D
