A person attempts to calculate the gravitational constant G by suspending two 100.0kg spherical masses from a high ceiling in a shopping mall and calculating the deflection of the cables from the vertical.
a) sketch a free body force diagram of one of the masses.
b) The cables are 45.0m long and attached to the ceiling 1.00m apart. What is the distance amnong of the two masses (centre of mass to centre of mass) at the bottom?
