A spherical metal shell A of radius `R_A` and a solid metal sphere B of radius `R_B(ltR_A)` are kept far apart and each is given charge `'+Q'`. Now they are connected by a thin metal wire. Then

A

`E_(A)^("inside")=0`

B

`Q_(A)gt Q_(B)`

C

`(sigma_(A))/(sigma_(B))=(R_(B))/(R_(A))`

D

`E_(A)^("on surface")lt E_(B)^("on surface")`
