I a uniformly positively charged sphere a very thin tunnel has been made along the diameter as shown in the figure below. A carged particle -`q` having mass m is released from rest at one end of tunnel. For the situation described, mark out the correct statement (s) : [Neglect gravity]

A

Charged particle will perform SHM about centre of the sphere as mean position

B

Time period of the particle is `2pi sqrt((4 pi epsi_(0) mR^(3))/(q Q))`

Particle will perform oscillation but not SHM

D

Speed of the particle while crossing mean positon is `sqrt((Qq)/(4 pi epsi_(0) mR))`

Suppose a smooth tunnel is dug along a straight line joining two points on the surface of the earth and a particle is dropped from rest at its one end. Assume that mass of the earth is uniformly distributed over its volume. Then, which of the following statements are not correct?

In a region of space a uniform magnetic field exist in positive z direction and there also exists a uniform electric field along positive y direction. A particle having charge + q and mass m is released from rest at the origin. The particle moves on a curve known as cycloid. If a wheel of radius R were to roll on the X axis, a fixed point on the circumference of the wheel would generate this cycloid. Find the radius R. It is given that strength of magnetic and electric fields are B0 and E0 respectively.
