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

A

`mu_(1) =0 , mu_(2) cancel(=) 0` and`N_(2) tan theta = (mg)/( 2)`

B

`mu_(1) cancel(=)0,mu_(2)= 0 ` and`N_(1) tan theta=(mg)/( 20`

C

`mu_(1)cancel(=)0 , mu_(2) cancel(=) =` and`N_(2) =( mg)/(1+ mu_(1) mu_(2))`

D

`mu_(1) = 0 , mu_(2) cancel(=)0` and `N_(1) tan theta =( mg)/(2)`
