Question

The distance between the midpoints of two metal balls,P and Q,respectively of masses 55 kg and 70 kg,is 80 cm (a)calculate the gravitational force that P exerts on Q thanks in advance

Answer 1

d = .8 meter
so
F = G *55*70 /(.64)
where G = 6.67*10^-11 m^3 /(kg s^2)

Answer 2

I'm looking for physical sciences solutions.
