This is a practice assignment and I just want to know if I did it correctly please show steps so I know I fed it correctly.

Gravitational Fields Assignment 1. a. What is the gravitational field strength at a point 1000 km above the surface of the Earth? b. What will be the gravitational force on a 5.00 kg mass placed at this point? 2. a. What is the net gravitational field at a point midway between the Earth and the moon? b. At what point between the Earth and the moon will the net gravitational field be zero? Electric Fields Assignment 1. a. What is the strength of an electric field at a point 3.00 cm left of a charge of -50.0 / C? b. What will be the force on a -1.00 / C charge placed at this point? 2. Charge A, -5.00 / C is 4.00 cm left of charge B, -4.00 / C. Calculate the electric field midway between the 2 charges
