Question

A block of weight 100N is lying on a rough horizontal surface. If coefficient of friction 1/square root of 3 then the least possible force that can move the block

Answer 1

Answer:

The maximum static frictional force offered by the floor will be

f₅ = μ₅mg = $\frac{1}{\sqrt{3}} * 100N = \frac{100}{\sqrt{3}} N$

$\frac{100}{\sqrt{3}} N$ is the least possible force to move the block

Answer 2

Answer:

50 N
