If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
