Question

If g is acceleration due to gravity on earth what is the acceleration of twice the earth radius

Answer 1

Answer:

1/4 of g or g/4

Explanation:

Eqn for g

g= GM/R^2

Given the radius is to be twice that of earth

Thus g'= GM/(2R)^2

= GM/4R^2

= g/4

For value pls substitute the values onto the eqn
