Twenty seven identical drops of mercury are charged to the same potential 10 volts. What will be the potential, if all the drops are combined to form one large drop ?

When two water drops merge to form a large drop

A number of small drops of mercury condense isothermally to form a single drop. What will be the effect on temperature of the drop?

Two copper spheres of same radii, one hollow and the other solid, are charged to the same potential. Which, if any, of the two would hold more charge ?

A number of small drop of mercury coalesce adiabatically to form a single drop. The temperature of the drop.

27 identical drops of water are falling down vertically in air with a terminal velocity 0.15 m//s . If they combine to from a single bigger drop, what will be its terminal velocity.

Two equal drops of water are falling through air with a steady velocity of 10 cm/s. If the two drops recombine to a single drop, what will be the terminal velocity

Two particles-one of mass m1, and the other of mass m2, carry equal charges. After being accelerated through the same potential difference they enter a region of uniform magnetic field and describe circular paths of radius (r_1) , and (r_2) , respectively. Find the ratio of their masses.
