1.	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]
Answer» Charged particle will perform SHM about centre of the sphere as MEAN position Time period of the particle is `2pi sqrt((4 PI epsi_(0) mR^(3))/(q Q))` Particle will perform oscillation but not SHM Speed of the particle while crossing mean POSITON is `sqrt((QQ)/(4 pi epsi_(0) mR))` ANSWER :A::B::D
