List of top Physics Questions on laws of motion asked in TS EAMCET

A body of mass 3 kg is kept on a rough horizontal surface. A horizontal force of 20 N acting on the body produces an acceleration of $4 ms^{-2}$ in the body. To double the acceleration of the body, the horizontal force applied is to be increased by

A block of mass $\sqrt{2}$ kg is placed on a rough horizontal surface. A force 'F' acting upwards at an angle of 45$^\circ$ with the horizontal causes the block to start motion. If the coefficient of static friction between the surface and the block is 0.25, the magnitude of the force 'F' is (Acceleration due to gravity = 10 ms$^{-2}$)

A truck of mass 8 ton is carrying a block of mass 2 ton. If a breaking force of 25 kN is applied on the truck, then the frictional force acting on the block is (Coefficient of static friction between the block and the truck is 0.3)

A force separately produces accelerations of 18 ms⁻², 9 ms⁻² and 6 ms⁻² in three bodies of masses P, Q and R respectively. If the same force is applied on a body of mass P+Q+R, then the acceleration of that body is
