Question 3 of 10 Coulomb's law describes how the charge on and distance between two
particles affect the electric force between them. Which situation will result in
the two particles being repelled by each other?
A. Both particles having a negative charge
O
B. Decreasing the distance between them
O
C. One particle having a positive charge and the other a negative
charge
D. Increasing the distance between them

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.

If there's a small amount of friction between two surfaces, the result could be select all that applya. no movement b. heatc. a little bit of movementd. sliding around
