A) \[mg\]
B) \[\frac{mg}{e}\]
C) emg
D) \[\frac{em}{g}\]
Correct Answer: B
Solution :
(b) \[\frac{mg}{e}\] Mass of water drop = m Weight of water drop = mg \[\because \]mg = electrostatic force applied by the field \[\therefore \,\,\,mg=qE=eE\] \[\Rightarrow \,\,E=\frac{mg}{e}\]You need to login to perform this action.
