question archive A negative charge (q- -0
Subject:PhysicsPrice:2.85 Bought3
A negative charge (q- -0.75 Coulombs) is placed above a loor that has a net positive charge. The floor creates a uniform electric field that has a magnitude of 105 N/C. What is the magnitude and direction of the electric force caused by the floor on the negative charge? a) b) Ifthe charge is initially at a distance 2.5 m above the plane, what will the change in electric potential energy (in Joules) be if it is then moved to a distance 1.5 m above the plane (specify whether this change is positive/negative/zero)?
