Answer:g=9.79
ms^(-2),
A object of mass
m at the surface of earth experiences a force
mg

Step-by-step explanation:

Let
M be the mass of earth.

Let
R be the radius of earth.

Let
G be the universal gravitational constant.

Given,


M=5.96* 10^(24)Kg


R=6.37* 10^(6)m


G=6.67259 * 10^(-11)
Nm^(2)Kg^(-2)

Let
g be the acceleration due to gravity.

Then,
g=(GM)/(R^(2))


g=(6.67259 * 10^(-11)* 5.96* 10^(24))/((6.37* 10^(6))^(2))


g=9.79ms^(-2)

A object of mass
m at the surface of earth experiences a force
mg
