Two uniformaly charged nonconducting spheres, each of radius R,are fixed in a gravity free space as shwon in the figure. If an electron is released at rest from the point A, then its speed just before striking the other sphere is [mass of electron `=m_(e)`]

If the masses are released from the position shown in figure then the speed of mass m1 just before it strikes the floor is -

A solid uniformly charged ficed non-conducting sphere of total charge Q and radius R contains a tunnel of negligible diameter. If a point charge '-q' of mass 'm' is released at rest from point P as shown in figure then find out its velocity at following points (i) At the surface of sphere (ii) At the centre of the sphere

A charge +Q is distributed uniformly throughout the volume of a fixed non- conducting sphere of radius R .Sphere is placed in a gravity free space and a narrow tunnel is made into it upto depth (R)/(2) .Outside the tunnel there is a spring of spring constant k .A small test charge of mass m and charge q is placed at the bottom of the tunnel at rest and is set free.The maximum compression of the spring is sqrt((aQq)/(16 pi varepsilon_(0)kR)) ,a is equal to (maximum compression in spring << R

Three solid spheres each of mass m and radius R are released from the position shown in Fig. What is the speed of any one sphere at the time of collision?

A sphere of mass m and radius r is projected in a gravity free space with speed v. If coefficient of viscosity of the medium in which it moves is 1/(6pi) , the distance travelled by the body before it stops is
