At a certain distance from a charged particle, the magnitude of the electric field is 460 V/m and the electric potential is -3.60 kV. (a) What is the distance to the particle? (b) What is the magnitude of the charge?

(a) the distance to the particle is 7.83 m

(b) the magnitude of the charge is 3.13 x 10⁻⁶ C

Explanation:

Given;

magnitude of the electric field, E = 460 V/m

magnitude of the electric potential, V = 3.6 kV = 3,600 V

(a) the distance to the particle is calculated as;

Er = V

r = V/E

r = 3,600/460

r = 7.83 m

(b) the magnitude of the charge is calculated as;
