Question

g=Gm /R^2

Can anyone solve this equation by putting universal values of g,G,m,R

Answer 1

hey buddy,

in solving this question we should know their values first.

here,
g is acceleration due to gravity,
G is gravitational constant = 6.67 × 10-¹¹
m is the mass of earth = 6 × 10²⁴
r is the radius of the earth = 6.4 × 10^6(/this vary at different points or places in the earth)

so now putting these values

g = Gm/R²
g = 6.67 × 10-¹¹ × 6 × 10²⁴ /(6.4 × 10^6)²
g = 9.81 approx which is approximately equal to the acceleration due to gravity of earth.

hope it will help

Answer 2

GRAVITATIONAL CONSTANT = 9.8 m/s^2
MASS OF EARTH = 5.96* 10 ^24 kg
RADIUS OF EARTH = 6.37*10^6 m

g = Gm /R^2

g= 9.8 * 5.96 / (6.37*10^6) ^2
g= 58.11 / 4.05 * 10^13
g = 14.34 * 10 ^ - 13 kg m^-1 s^-2
