Question

The electric force experienced by a -2.2 μC charge at some point P has a magnitude of 19.2 N and points due North.

a. What is the magnitude of the electric field, in newtons per coulomb, at P?

b. What is the magnitude of the force, in newtons, that an electron would experience if it were placed at point P instead of the given charged particle?

c. If a proton were placed at point P instead of the electron, what is the magnitude of the force, in newtons, that it would experience?

d. What is the ratio of the magnitude of the acceleration of an electron to that of a proton, when the electric field acting on each has the same strength?
