One person is pulling a box toward the left with a force of 350 N. The other person is pushing on the same box to the left with a
force of 210 N. What is the effect of these forces on the box?

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
