Question: an electron is 014cm from an object with electric charge...
An electron is 0.14cm from an object with electric charge of + 3.0 *10^-6 C.
A) Determine the magnitude of the electrical force Fo on e that the object exerts on the electron.
B)The electron is pulled so that it moves to a distance of 0.14cm from the charged object. Determine the magnitude of the electrical force F ' o on e exerted by the charged object on the electron when at this distance.
C) Estimate the work done by the average force pulling the electron ( (FOone+F?Oone *?x)/2)
D) Determine the change in electric potential energy of the electron-charged-object system as the electron moves away from the object.
