SUMMARY
The gravitational attraction between two students with masses of 70 kg and 50 kg, separated by a distance of 1.5 m, is calculated using the formula Fg = Gm1m2/r^2. The gravitational constant G is 6.67 x 10^-11 N(m/kg)^2. Plugging in the values, the resulting force is approximately 1.56 x 10^-9 N, confirming that the gravitational pull is indeed very small.
