1.) Two objects have masses of 300 kg and 500 kg. Their centers are separated by distance of 25 m. Find the gravitational attraction between them.
Given:
m1=300 kgm_1=300\:\rm kgm1=300kg
m2=500 kgm_2=500\:\rm kgm2=500kg
r=25 mr=25\:\rm mr=25m
G=6.67∗10−11 N⋅m2/kg2G=6.67*10^{-11}\:\rm N\cdot m^2/kg^2G=6.67∗10−11N⋅m2/kg2
