JEE AdvancedPhysicsLaws of MotionMultiple correct+4 / −2
A small block of mass 0.1 kg lies on a fixed inclined plane PQ which makes an angle θ\thetaθ with the horizontal. A horizontal force of 1 N acts on the block through its centre of mass as shown in the figure. The block remains stationary if (take g = 10 m/s2) IIT-JEE 2012 Paper 1 Offline Physics - Laws of Motion Question 8 English
