Which describes time dilation? the faster an object moves, the more stretched time becomes. the more slowly an object moves, the more stretched time becomes. the faster an object moves, the more time it takes for light to travel a given distance. the faster an object moves, the less time it takes for light to travel a given distance.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
