Question

spherical metal shell A of radius Ra and solid metal sphere B of radius Rb are given charge +Q and are then connected by a thin metallic wire. Which of the following are true? A.Qa>Qb B.EA c.SIGMA A/SIGMA B =Rb/Ra sigma is surface charge density Ra>Rb

Khimraj · Answer

Both sphere are connected by thin metallic wire. So there surface will be at same potential . then KQ a /R a =KQ b /R b then Q a /R a =Q b /R b (Q a /4 π R a 2 )4 π R a = (Q b /4 π R b 2 )4 π R b Then ( a )R a = ( b )R b So a / b = R b /R a. Hope it clears. If you like answer then please approve it.
