Electric Field Quiz

(3 points each)

- Draw the electric field lines between two plates that have the same charge.
- (T/F) Electric fields become stronger as you leave the object emitting the field.
- (T/F) The electric field on the inside of a sphere is zero.
- (T/F) The distance between electric field lines represent the fields strength.
- Draw the electric field around a triangular shape that has a charge.

6) Calculate the field strength at .9 m away from the red negative .0003C charged sphere

7) Find the force on the blue positive .2C charge that is placed in a 20N/C electric field

8) How many excess electrons are on the red negative sphere?

(hint: the charge of one electron is 1.6 x 10-19 C)
