An electron m 9109 x 10-31kg is in the presence of a, Ask an Expert

Academics

An electron (m = 9.109 x 10^-31kg) is in the presence of a constant electric field E. The electron has a charge of e = 1.602 x 10^-19 C and it accelerates at a rate of a = 7800 m/s2.

Part (a) Write an expression for the magnitude of the electric field.

Part (b) What is the field, in units of N/C?

Part (c) Assuming the electron begins at rest, what is its velocity after 4 s? Give your answer in meters per second.
