If a body of 2kg mass is at a distance of 7200km from the center of the earth .What would the acceleration due to gravity beat this point in the earthfield.(A)9.6m/s2(B)

10.0m/s2(C)11.3m/s2(D)12.7m/s2(E) 15.6m/s2

None of the choices is correct.

== The Earth's radius is 6,371 km.  That's how far you are from the center of the Earth when you're on the ground.

== The acceleration of gravity on the ground is 9.8 m/s² .

== The acceleration of gravity varies inversely as the square of the distance from the center of the Earth.  So, at 7,200 km from the center, it's

(9.8 m/s²) · (6371km/7200km)² .

Stuffing this through your cakulator, you'll get  7.67 m/s² .
