A block of weight `W` is held against a vertical wall by applying a horizontal force of `75N` . The surface3 of the wall is rough. Now (conside `mult1)`

A

`Wlt75N`

B

`W=75N`

C

`Wgt75N`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
If `W` is in equilibrium `f=W` But we know `flemuR` or `(Wlemu(75)`
or `75ge(W)/(mu)` implies`75=(W)/(mu)`
or `75gt(W)/(mu)`
But mu is generally less than 1
:. `Wlt75N` .
