Question

prove that g=G m*m/d^2 with suitable example​

Answer 1

Actually, g = Gm/d^2

Answer 2

Answer:

EXAMPLE...

Explanation:

Since the gravitational field g = F/m, in general g has a magnitude of GM/r2 and points toward M. This gives us the value of 9.8 m/s2 we've been using all along:

M = mass of the Earth = 5.98 x 1024 kg

R = radius of the Earth = 6.37 x 106 m

g = 9.83 m/s2

F = Gmm/R²

Mg = Gmm/R²

g = Gm/R²

= 6.67 × 10-¹¹ × 5.98 × 10²⁴ / (6.37 × 10⁶)²

= 9.8 .. Hence proved...
