Question

if an electric field balance the weight of an electron,find the field intensity?​

Answer 1

Answer:

please mark me as brainliest

Explanation:

The force of gravity on the electron will be = mg where m is the mass of the electron (about9 x10^-31kg). Now ther force on an electron due to an electric field (E) is F=qE where q is the charge on an elrctron (about 1.6 x10^-19 C). rearrange E = mg/q now substiytute in the values and work out the answer.
