Use Coulomb's law to determine the magnitude of the electric field at points AandB in( Figure 1 )due to the two positive charges( Q = 4.9 C )shown....

Qμ) shown. Suppose that a

Part A - Determine the magnitude of the electric field at A.

Ea = ???

Part B - Determine the angle between the direction of the electric field at point A and the positive x-direction.

θA

Part C - Determine the magnitude of the electric field at point B.

EB

Part D - Determine the angle between the direction of the electric field at point B and the positive x-direction.
