A charged particle q1 = 7.00 C is located at the origin and a charged particle q2 = -5.00 C is located at (0.300 m, 0).
What is the net electric field (unit-vector notation, magnitude, direction) at a point P located at (0, 0.400 m)?
What is the net electric force (unit-vector notation, magnitude, direction) on a charged particle q3 = -3.00 C located at P?
please solve asap.
You stand at location A, a distance d from the origin, and hold a small charged ball. You find that the electric force on the ball is 0.056 N. You move to location B, a distance 2d from the origin, and find the electric force on the ball to be 0.007 N. What object located at the origin might be the source of the field? (Select all that apply.)
