Question

The weight of a 0.6 kg object at the surface of Planet V is 20 N. The radius of the planet is 4 X 10⁶ m. Find the gravitational acceleration at a distance of 2.0 X 10⁶ m from the surface of this planet.

9 m/s²

13 m/s²

14.8 m/s²

11 m/s²

Answer 1

Solution :-

The mass of the object = 0.6kg , weight = 20 N .

We know, gravitational acceleration is inversely proportional to the square of the distance between the centre of the planet and the object.

So the gravitational acceleration at the given distance is 14.8 m/s^2.
