−31
kg. Charge on the electron =1.6×10
−19
coulomb and g=9.8m/s
2
. Then the intensity of the electric field required to balance the weight of an electron is -

Answer 1

Explanation:

here E called intensity of the electric field qe is called charge of the electron and me is called mass of the electron g is called acceleration due to gravity finally we get the answer please check your answer my friend
