Question 292981: I have tried several times to figure this one out...Any help with this would be greatly appreciated! Thanks!

The weight of an object on a small planet in Alpha Centauri is governed by the following equation:
w=c*r^-1/2
Here, C is a constant, and r is the distance that the object is from the center of the planet.
Solve the above equation for r.
