Hello friends, I have a question considering newton in circular motion.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass m and radius of orbit L.

What is the net force of every single satellite?

e.g. - S1: m= 300kg L= 7500m

If I know how to work one of them out I can do the rest.

2. Relevant equations

F = mv^2/L

I know m, know L but have to figure out v.

3. The attempt at a solution

Well, I started writing down the equation for motion in a circle and got Fnet=mv^2/L.

I was hoping I could replace v with 2*pi*L/T.

However I dont know T. I am assuming that since the time taken for the round trips is the same for every satellite, I could assume T being 1 couldnt I?

Please help and thanks in advance.
