Motion Of Blocks When Connected With String MCQ - Practice Questions with Answers

A block of mass M  is pulled along a horizontal frictionless surface by a rope of mass m. If a force F is applied at the free end of the rope, the force  exerted by the rope on the block is:

Three blocks of masses 6kg, 4kg, and 2kg kept on a smooth surface connected together with light strings are pulled applying 24N horizontal force as shown in the figure. The tension T₁ in the string is- (in N) 

In the given figure, three blocks are connected by masses of cords. Masses of the block are $\mathrm{m},3\mathrm{m}$ and 5 m and they are pulled by a force F on a frictionless horizontal surface. If the tension ${\mathrm{T}}_1=16\mathrm{N}$ then ${\mathrm{T}}_2$ is equal to-

A string is wrapped around a solid cylinder and then the end of the string is held stationary, while the cylinder is released from rest. The acceleration of the cylinder and tension in the string -
