Question 213: Laws of Motion

Question

A block of mass 2 kg is placed on inclined rough surface AC (as shown in figure) of coefficient of friction $$\mu$$. If g = 10 m s$$^{-2}$$, the net force (in N) on the block will be:

Accepted Answer

$$\mu=\frac{1}{\sqrt3}$$
$$	an30^\circ=\frac{1}{\sqrt3}$$
as $$\mu=	an	heta$$
the block is at rest and net force on it must be zero.

Answer

10$$\sqrt3$$

Answer

zero

Answer

10

Answer

20
