When a spaceship is two earth radii distant from the centre of the earth, its gravitational acceleration is:

Question

Philoid · Accepted Answer

We know that,

Where,

G = Gravitational Constant = Nm²kg^-2

M = Mass of Earth

R = Radius of Earth

Now, the spaceship is at a distance R’ = 2R

So, g will be:

ms^-2

Hence, option D is correct.
