Physics · LAWS OF MOTION
हिन्दीA block of mass \( m \) is pulled along a horizontal rough surface (\( \mu_s \)) by a horizontal force \( F \). The normal force exerted by the surface on the block is:
Correct answer · Option 3
\( mg \)
Explanation
Since the applied force is horizontal, vertical equilibrium gives \( N - mg = 0 \implies N = mg \).
