Question

A cubical wooden box of side $L$ is placed on a horizontal rough surface and the coefficient of static friction between them is $\mu$. Another cubical box of same wood but of length $2L$ is placed on the same surface. Then the coefficient of static friction is

• A. $8\mu$
• B. $4\mu$
• C. $2\mu$
• D. $\mu$

Answer 1

The correct option is D $\mu$

Coefficient of friction depends on the nature of surfaces in contact and independent of length or the surface area
