A star that is at hydrostatic equilibrium pulls in a large amount of extra
hydrogen. Is the star likely to remain the same
size or not? If not, will it get larger or smaller?
Please explain your answer.

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
