Question

A block of weight $100$ $N$ is lying on a rough horizontal surface. If coefficient of friction $\frac{1}{\sqrt{3}}$. The least possible force that can move the block is

• A. $\frac{100}{\sqrt{3}}$
• B. $100\sqrt{3}$
• C. $50\sqrt{3}$
• D. $50N$

Answer 1

The correct option is A $\frac{100}{\sqrt{3}}$

We have formula

$F_{min}-\mu N$

Here $\mu =$ coefficient of function $=\frac{1}{\sqrt{3}}$

and $N=100N$

So $F_{min}=\frac{100}{\sqrt{3}}$ ans
