Question

An electron in a region where there is an electric field experiences a force of magnitude 3.5 10-16 n. what is the magnitude of the electric field at the location of the electron?

Answer 1

The force that an object feels in an electric field is the magnitude of the electric field E times the charge on the object Q. We know that the magnitude of the charge of an electron is 1.6 x 10^{-19} C F = E x Q E = F / Q E = (3.5 x 10^{-16} N) / (1.6 x 10^{-19} C) E = 2.19 x 10^3 N/C The magnitude of the electric field at the location of the electron is 2.19 x 10^3 N/C
