Two brass plates are arranged horizontally , one 2 cm above the other. The plates are charged to a potential differnece of 6600 V. Now very fine liquid drops are sprayed into the space between the plates . Big drops collect at the bottom plate some drops go up and some remain statinary . How do you explain this ? If the radius of the stationary drops is `2 xx 10^(-6)` m and density of liquid 800 `kgm^(-3)` , calculate the charge carried by the stationary drops. Does this result confirm quantisation of charge?
