NEETPhysicsLaws of MotionMCQ+4 / −1

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

Correct answer: B

NEET 2023 Manipur Physics - Laws of Motion Question 5 English Explanation

$\mu=\frac{1}{\sqrt3}$

$$\tan30^\circ=\frac{1}{\sqrt3}$$

as $\mu=\tan\theta$

the block is at rest and net force on it must be zero.
