Question

EXAMPLE 3.4: Calculate the value of acceleration due to gravity on the surface of the earth. Given that mass of the earth = 5.98 x 1024 kg, radius of the earth = 6.37 * 106 m and G = 6.67 x 10-11 N m² kg-2. ​

Answer 1

Answer:

Step-by-step explanation:

we know

g = GM/R²

where g = acceleration due to gravity

G = Gravitational constant

M = mass of earth

R = radius of earth

g = GM/R²

M = gR²/G

M = 9.8 x 6.4 x 10^12 / 6.67 x 10 -11

M = 6.018 x 10^24 kg
