- two identical lead spheres have a combined mass of 12kg. the density of lead is 11400 kg m-3. find the radius of each sphere. calculate the gravitational force of attraction between the 2 spheres when they are touching.

-two masses, one of 300g and one of 500g are placed 40cm apart and a 75g mas is placed midway between them. find the magnitude and direction of the other resultant gravitational force acting on the 75g mass produced by the presence of the other masses.
