A +5.0uC charge experiences a 0.48N force in the positive y direction.
If this charge is replaced with a 2.7uC 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.
