# 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>QbB.EAc.SIGMA A/SIGMA B =Rb/Rasigma is surface charge densityRa>Rb

Then  ($\sigma$a)Ra = ($\sigma$b)Rb
So $\sigma$a/$\sigma$b = Rb/Ra.
