and value of g is 9.8 m/s2
hope it will help u if so plz mark brainliest
The Gravitational Constant(G)
➡️It is numerically equal to the Gravitational force between two unit masses kept unit distance apart.
➡️The value of G is 6.67×10^-11 Nm^2 kg^-2
Acceleration due to gravity(g)
➡️The value of g is 9.8 m/s^2
Since g= G×M/R^2
=>g=(6.7×10^-11×6×10^24)/(6.4×10^6)^2
=>g=9.8m/s^2
where G= Gravitational Constant
M=Mass of Earth
R=Radius of Earth
➡️The value of g varies due to the following factors:
(i) g varies with altitude(g decreases with increase in height above the earth surface).
(ii) g decreases with depth
(iii) g varies with the shape of the earth
➡️The value of g decrease when we go above the surface of the earth.
g'=g(R/R+h)^2
➡️The value of g decreases with depth. At a height d below the surface of earth,
g'=g{1-(d/R)}
Hope it helps✌️✌️
