A 7055 kg satellite is orbiting Earth where it is experiencing a gravitational field
strength of 1.82 N/kg.
(mass of the earth is 5.97 x 10 24 kg and radius of the earth is 6.38 x 10 6 m)
a) Determine the distance between the satellite and the centre of the Earth. [2]
b) Determine the satellites altitude. [1]
c) Determine the Force of gravity acting on the satellite at this position. [1]

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
