q1= 25 pC q2 = -75 pC

A) calculate the magnitude of the electric force between the two charges

B) Is the force attractive or repulsive?

C) calculate the magnitude and direction of E1 *( there is an arrow above E1) , the electric field at the orgin due to charge q1.

D) calculate the magnitude and direction of E2 ( there is an arrow above E2), the electric field at the orgin due to charge q2

E) Calculate the magnitude and direction of the total electric field E ( arrow is above the E) at the orgin and the force F ( arrow above the F) that it would exert on a charge q3 = 20 pC placed at the orgin
