A +5.0-uC charge experiences a 0.48-N force in the positive y direction.
If this charge is replaced with a -2.7-uC charge, find the magnitude of the force in this case
Find the direction of the force in this case.
help please i am confused
The direction will be opposite (-y) because the sign of the charge is reversed (positive to negative).
The magitude of the force will be (2.7/5.0) times 0.48 N. It is proportional to the charge.
The local electric field where the chrges are located is assumed to stay the same.
