## Homework Statement

A student attempts to measure the gravitational constant G by suspending two 100.0kg spherical masses from a high ceiling in a shopping center and measuring the deflection of the cables from the vertical.

The cables are 45.0m long and attached to the ceiling 1.00m apart. What is the distance between of the two masses (center of mass two center of mass) at the bottom?

## Homework Equations

F = (Gm1m2)/(r^2)

W=mg

## The Attempt at a Solution

I worked out that the force between the two when they are 1m apart is 6.67*10^-7 and the weight of the spheres is 980N. I know that the weight is a vertical component and the force is a horizontal component but I'm unsure how I can use the force to calculate the distance between them.

Thanks for the help
