A car weighs 6000 N on the Earth's surface, what is its weight 3 times Earth's radius away from the center of the Earth? (N)

667 N

Explanation:

And we need to find out the weight of the car at a distance equal to 3 times the radius of the earth , from the centre of the earth.

We can find the acceleration due to gravity at a height h from the earth's surface as ,

In above equation multiply both sides by m ,

Now here at the place of mg we can substitute 6000N , and mg will be the weight at height h which we are interested in finding .
