Question

a mass of 40 kg is attracted by a mass of 25kg lying at a distance of 2 metres from it with a force of 1.67 into 10 power of -8N.find the value of G​

Answer 1

Explanation:

F = GmM/r^²

1.67*10^(-8) = G (40*25/4)

1.67*10^(-8) = G *250

G = 1.67/250*10^(-8)

= 6.68 × 10^(-11) (Nm^2)(kg)²
