A ladder rests against a frictionless vertical wall, with its upper end `6 m` above the ground and the lower end `4 m` away from the wall. The weight of the ladder is `500 N` and its `CG` at `1//3^(rd)` distance from the lower end. Wall's reaction will be (in newton)

Options

A. 111
B. 333
C. 222
D. 129

Answer

A

Explanation

Since whole system is in equilibrium, taking moment of forces about B

`Rxx6=500xx(4)/(3)`
implies `R=(1000)/(9)`
implies `R=111.1 N`
