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
What is your question here?
Coulombs laws apply.
