solve Q 33 33.A block of mass 3 kg is at rest on a rough inclined plane as shown in the figure. The magnitude of net force exerted by the surface on the block will be (g = 10 m/s2) (A) 26 N (B) 19.5 (C)10N (D) 30 N Share with your friends Share 6 Shobhit Mittal answered this Dear Student, since the block is in rest and the only force that counter the weight of the block is the contact force that is normal rxn and the frictional force so the addition of these two contact force is such that it will be equal to weight .hence the force exerted by the surface is 30 N that is equal to the weight of the block .Option DRegards 8 View Full Answer
