Calculate the electric field strength which is required to just support a water drop of mass `10^(-3)` kg and having a charge `1.6xx10^(-19)C`.

Text Solution

Verified by Experts

Here, `m = 10^(-3)kg, q = 1.6xx10^(-19)C`
Force on water drop due to electric field = weight of water drop
`qE = mg`
`:. E = (mg)/(q) = (10^(-3)xx9.8)/(1.6xx10^(-19)) = 6*125xx10^(16) N//C`
