A spherical shell of radius R_(1)with a uniform charge q has a point charge q has a point charge q_(0) at its centre. Find the work performed by the electric forces during the shell expansison from radius R_(1) to radius R_(2)

Answer»

`W=(q(q_(0)+q//2))/(2piepsilon_(0))((1)/(R_(1))-(1)/(R_(2)))`
`W=(q(q_(0)+q//2))/(piepsilon_(0))((1)/(R_(1))+(1)/(R_(2)))`
`W=(q(q_(0)+q//2))/(4piepsilon_(0))((1)/(R_(1))-(1)/(R_(2)))`
`W=(q(q_(0)+q//2))/(4piepsilon_(0))((1)/(R_1)+(1)/(R_(2)))`
