Acceleration Of Block On Horizontal Smooth Surface MCQ - Practice Questions with Answers

A force of 50N acts in the direction as shown in fig. The block of mass of 5kg resting on a smooth horizontal surface . What is the acceleration of the block?

In fig, if the surfaces are frictionless then tension $T_2$ (in N ) will be:

Two blocks of mass 5 kg and 5 kg are connected by a string of mass 2 kg as shown in fig. Point Q is the midpoint of the string. A pulling force of 24 N is applied on block 5 kg at an angle of ${60}^{\circ }$ with horizontal. The tension (in N ) at point Q is (all surfaces are frictionless).

At time $t=0$, a force $F=kt$ where k is any constant, is exerted on a small body with mass $m$, which is initially at rest on a frictionless horizontal surface. The resultant direction of the applied force forms an angle of ${90}^{\circ }$ with the horizontal plane. Find the velocity of the body at the moment of its breaking off plane.

A horizontal force of 10 N is applied to block A as shown in the figure. The mass of blocks A and B are 2 kg and 3 kg respectively. The blocks slide over a frictionless surface. The force exerted by block A on block B is :
