Chapter:
A charged oil drop of mass `5**10^-15\ kg` falls vertically in air with steady velocity between two long parallel vertical plate 5 mm apart. when a potential difference of 500 volt is applied between plates , drop now falls with a steady velocity at an angle 45 degree to vertical. What is charge on oil drop?
