A body having specific charge `8 mu C//g` is resting on a frictionless plane at a distance 10 cm from the wall (as shown in the figure). It starts moving towards the wall when a uniform electric field of 100 V/m is applied horizontally towards the wall. If the collision of the body with the wall is perfectly elastic, then the time period of the motion will be ______ s.

A block having mass 'm' ad carge q is resting on a fractionless plane at distance L from the wall as shown in fig.Discuss the motion of the block when a uniform electric field E is applied horizontally towards the wall assuming that collision of the block with the wall is perfectly elastic.

A block having mass m and charge Q is resting on a frictionless plane at a distance d from fixed large non-conducting infinite sheet of uniform charge density -sigma as shown in Figure. Assuming that collision of the block with the sheet is perfectly elastic, find the time period of oscillatory motion of the block. Is it SHM ?

A sphere of mass m slides with velocity v on as frictionless surface towards a smooth inclined wall as shown in figure. If the collision with the wall is perfectly elastic find a. the impulse imparted by the wall on the sphere b the impulse imparted by the floor on the sphere.

A vessel contains 6xx 10^(26) molecules m ^(-3). Mass of each molecule is 6xx10^(-27) kg. Assume that, on an average, one-sixth of the molecules move with a velocity 10^(3) m/s perpendicularly towards each wall. If the collisions with the walls are perfectly elastic, then which of the following is correct?

In the figure, the block of mass m, attached to the spring of stiffness k is in correct with the completely elastic wall, and the compression in the spring is e. The spring is compressed further by e by displacing the block towards left and is then released. If the collision between the block and the wall is completely eleastic then the time period of oscillation of the block will be

A block is attached to a spring and is placed on a horizontal smooth surface as shown in which spring is unstretched. Now the spring is given an initial compression 2x_(0) an block is released from rest. Collision with the wall PQ are elastic. Find the time period of motion of the block:

Figure shown a block P of mass m resting on a smooth horizontal surface, attached to a spring of force constant k which is rigidly fixed on the wall on left side, shown in the figure . At a distance l to the right of the block there is a rigid wall. If block is pushed towards loft so that spring is comparessed by a distance 5l//3 and when released, if will starts its oscillations. If collision of block with the wall is consdered to be perfectly elastic. Find the time period of oscillation of the block.

Two balls each of mass 'm' are moving with same velocity v on a smooth surface as shown in figure. If all collisions between the balls and balls with the wall are perfectly elastic, the possible number of collisions between the balls and wall together is

A block of mass 100 g attached to a spring ofstiffness 100 N//Mis lying on a frictionless floor as shown. The block is moved to compress the spring by 10 cm and released. If the collation with the wall is elastic then find the time period of oscillations.
