Charges `Q_(1)` and `Q_(2)` lie inside and outside respectively of an uncharged conducting shell. Their separation is `r`.
(i) The force on `Q_(1)` is zero
(ii) The force on `Q_(1)` is `k((Q_(1) Q_(2))/(r^(2)))`
(iii) The force on `Q_(2)` is `k((Q_(1) Q_(2))/(r^(2)))`
(iv) The force on `Q_(2)` is zero
