Question

.A particle of charge 2 X 10^-19 C is placed in the upward electric field of 10 N/C. What is the direction of gravitational force on the charge particle?

Answer 1

The direction of gravitational force on the charge particle is downwards.

$$F_e=qE=(2\cdot 10^{-19})(10)=2\cdot 10^{-18}\ N$$
