A circular plate of radius r r is removed from a uniform circular plate P of radius 4r 4r to form a hole. If the distance between the centre of the hole formed and the centre of the plate P is 2r 2r , then the distance of the centre of mass of the remaining portion from the centre of the plate P is?
A hollow cylinder and a solid cylinder initially at rest at the top of an inclined plane are rolling down without slipping. If the time taken by the hollow cylinder to reach the bottom of the inclined plane is 2 2 s, the time taken by the solid cylinder to reach the bottom of the inclined plane is?
A block kept on a frictionless horizontal surface is connected to one end of a horizontal spring of constant 100 Nm−1 100 \, \text{Nm}^{-1} , whose other end is fixed to a rigid vertical wall. Initially, the block is at its equilibrium position. The block is pulled to a distance of 8 8 cm and released. The kinetic energy of the block when it is at a distance of 3 3 cm from the mean position is?
The ratio of the radii of a planet and the earth is 1:2 1:2 , the ratio of their mean densities is 4:1 4:1 . If the acceleration due to gravity on the surface of the earth is 9.8 ms−2 9.8 \, ms^{-2} , then the acceleration due to gravity on the surface of the planet is?
A ball P of mass 0.5 0.5 kg moving with a velocity of 10 ms−1 10 \, ms^{-1} collides with another ball Q of mass 1 1 kg at rest. If the coefficient of restitution is 0.4 0.4 , the ratio of the velocities of the balls P and Q after the collision is?
