A block weighs W is held against a vertical wall by applying a horizontal force F. The minimum value of F needed to hold the block is

Less than W

Equal to W

Greater than W

Data is insufficient

Text Solution

Verified by Experts

The correct answer is:

Here applied horizontal force F acts as normal reaction.

For holding the block

Force of friction = Weight of block

$f = W \Rightarrow \mu R = W \Rightarrow \mu F = W \Rightarrow F = \frac{W}{\mu}$

As $\mu < 1 :: F > W$
