Question

Derive the formula to calculate acceleration due to gravity.

(b) Calculate the value of acceleration due to gravity on the surface of a

satellite having a mass of 7.4 × 22 and a radius of 174 km and G = 6.7 ×

− ∕ .​

Answer 1

Explanation:

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.

Answer 2

Answer:

a) F=GM/R^2

Explanation:

b) g(accleration due to gravity)=?

G(gravitional constant)= 6.7×10^-11 Nm^2 kg^-2

M (mass of sattelite) = 7.4×10^22kg

R (radius of sattelite) =1.74×10^6 kg

g=GM/R^2

g= 6.7×10^-11×7.4×10^22/(1.74×10^6)^2

(10^22-11=10^11)

=6.7×7.4×10^11/1.74×1.74×10^12

= 16.376 × 10 ^-1

= 1.6ms^-2

answer : g=1.6ms^-2
