what is the acceleration due to gravity at a distance of 2 earth radii abouve earths surface?

g=9.8(1/3)^2

To calculate the acceleration due to gravity at a specific distance above Earth's surface, we can use the formula for gravitational acceleration:

a = G * (M / r^2)

Where:
a is the acceleration due to gravity,
G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2/kg^2),
M is the mass of Earth, and
r is the distance between the center of Earth and the object.

Given that the distance is 2 Earth radii above the Earth's surface, we need to determine the value of r.

Let's assume the radius of Earth is r_e. Therefore,

r = (2 + 1) * r_e

(Multiply by (2 + 1) because the distance is 2 radii above the surface, and we need to consider the radius of Earth as well.)

Once we have the value of r, we can substitute it into the formula to calculate the acceleration due to gravity.
