Question

At what distance from centre of earth acceleration due to gravity will be the value of g on the surface of earth? [R is radius of earth]

Answer 1

Answer:

from 6370 km

Explanation:

formula to find g is

g = GM/ R ( square )

where,

G - gravitational constant it's value is 6.67 * 10 raise to (-11) nm square/ kg raise to (2)

M - mass of the earth . which is 6*10 raise to (24) kg

R - radius of the earth . which is 6370 km

g- acceleration due to gravity ( in this case this is of earth) .It's value is 9.8066 m/s square
