512 identical drops of mercury are charged to a potential of 2V each. The drops are joined to form a single drop. The potential of this drop is ___ V.

125 identical drops each charged to the same potential of 50 volts are combined to from a single drop. The potential of the new drop will be

If n drops, each charged to a potential V, coalesce to form a single drop. The potential of the big drop will be

1000 drops of same size are charged to a potential of 1 V each. If they coalesce to form in single drop, its potential would be

Eight oil drops of same size are charged to a potential to 50 V each. These oil drops are merged into one single larged drop. What will be the potential of the large drop ?

There are 27 drops of a conducting fluid. Each drop has radius r , and each of them is charged to the same potential V_1 . They are then combined to from a bigger drop. The potential of the bigger drop is V_2 . Find the ratio V_2//V_1 . Ignore the change in density of the fluid on combining the drops.

If n drops of a liquid, form a single drop, then

Twenty seven drops of same size are charged at 220V each. They combine to form a bigger drop. Calculate the potential of the bigger drop.

27 small drops of same size are charged to V volts each. If they coalesce to form a single large drop, then its potential will be
