Question

Calculate the force per unit mass on the earth surface take g=6.67×10^‐11 Nm^2 kg^‐2 mass of the earth 5.98×10^24kg and radius 6.38 ×10^6

Answer 1

Answer:

Explanation:

F = GMm/$r^{2}$

Force per unit mass (1 kg wt) = GM(1 kg)/$r^{2}$

= (6.67 x 10^-11 x 5.98 x 10^24)/(40.7044 x 10^12)

= 0.979908806 x 10^(24-11-12)

= 0.979908806 x 10

= 9.79908806 N
