Two concentric, thin metallic spheres of radii `R_(1) and R_(2) (R_(1) gt R_(2))` charges `Q_(1) and Q_(2)` respectively Then the potential at radius r between `R_(1) and R_(2)` will be `(k = 1//4pi in)`

Options

A. `k((Q_(1) + Q_(2))/(r))`
B. `K((Q_(1))/(r)+(Q_(2))/(R_(2)))`
C. `k((Q_(2))/(r)+(Q_(1))/(R_(1)))`
D. `k((Q_(1))/(R_(1))+(Q_(2))/(R_(2)))`

Answer

C
