Question

What are the magnitude and direction of the electric force on an electron in a uniform electric field of strength 1920 N/C that points due east? A proton is released in a uniform electric field, and it experiences an electric force of 2.18 times 10^-14 N toward the south. What are the magnitude and direction of the electric field? Determine the magnitude and direction of the electric field 16.4 cm directly above an isolated 33.0 times 10^-6 C charge. A downward electric force of 8.4 N is exerted on a -8.8 mu C charge. What are the magnitude and direction of the electric field at the position of this charge?

Explanation / Answer

21)

electric field = 1920 N/C to the east

charge on the electron , q = -e

net force on the electron = charge * electric field

net force on the electron = 1.602 *10^-19 * 1920

net force on the electron = 3.08 *10^-16 N

the magnitude of force on electron is 3.08 *10^-16 N

as the charge is negative , the force will be oposite to field

the force on the electrons is to the west
