A GPS satellite has an altitude of h km. If the gravitational force between the Earth and the
satellite is 921.9 N, determine the value of h.
[Mass of satellite = 1630 kg, mass of the Earth
= 6x 10²⁴ kg, radius of the Earth = 6.4 x 10⁶m

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.

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
