Exercise 1

A string of negligible mass going over a clamped pulley of mass supports a block of mass M as shown in the figure. The force on the pulley by the clamp is given by

A uniform rope of mass $M$ and length $L$ is fixed at its upper end vertically from a rigid support. Then the tension in the rope at the distance $I$ from the rigid support is

A block of mass $2 \mathrm{kg}$ rest on the floor of an elevator. Which is moving down with an acceleration $\text{'}g\text{'}.$ Then the apparent weight of the block is (take, $g=10 \mathrm{m} {\mathrm{s}}^{-2}$ )

If the resultant force acting on a moving body is zero, then

Newton's first law is applicable

A block of mass $m,$ is kept on a wedge of mass $M,$ as shown in figure such that mass $m$ remains stationary $w.r.t.$ wedge. The magnitude of force $P$ is

The pulleys and strings shown in the figure are smooth and of negligible mass. For the system to remain in equilibrium, the angle $\theta$ should be
