I need help with this question please I don't understand, I need it by tomorrow please I'm desperate.

find the these

..... how do I find the net force with on the 1000kg satellite, if the distance from the center earth to the moon is 384 00km, and the mass of the moon is 7.36 × 10^22 kg when the satellite is halfway between them

... how do i find the acceleration of gravity  (grevitational field strength) happening on a Russian Space Monkey orbiting the Earth 250km above the surface of the Earth.

 

also, can someone tell me how to find the tension? ex.having 10 mass (uk=0.55) and 3.5m/s^2

please show the procedure so I can do it on my own once again. thanks a lot
