A uniform electric field exists everywhere in the x, y plane. This electric field has a magnitude of 4500 N/C and is directed in the positive x direction. A point charge -5.5 × 10-9 C is placed at the origin. Find the magnitude of the net electric field at (a) x = -0.20 m, (b) x = +0.20 m, and (c) y = +0.20 m.

Excuse ! extra points plus ! super desperate ! the position of an object does not move relative to a reference point. relative to the reference point the object _. a.) is not moving. b.) is moving.

In physics the desire of an object to keep doing what it is doing is termed?
