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)

A

Text Solution

Verified by Experts

The correct Answer is:
A
Since whole system is in equilibrium, taking moment of forces about B
`R xx 6= 500 xx (4)/(3)`
`rArr R= (1000)/(9)`
`rArr R= 111.1 N`
