A negative charge (q= -0.25 coulombs) is placed above a floor that has a net positive charge. The floor creates a uniform electric field that has a magnitude of 100N/C.
a). What is the magnitude and direction of the electric field ont he negative charge?
b). If the charge is initially at a distance 3.0 m above the plane, what will the change in electric potential energy (in Joules) be if it is then moved to a distance of 1.0 m above the plane (specify whether this charge is positive/negative/zero)?
