Find the acceleration due to gravity on the surface of (a)

Step 1 of 3

Here we need to find the acceleration due to gravity on the surface of venus and mercury.

First we need to use the universal law of gravitation.

------------------(1)

Where is the universal gravitational constant, whose value is,

.

M is the mass of the planet and m is some arbitrary mass near the surface of the planet.

r is the distance between the centre of the planet and the object.

F is the force between the planet and the object.

We also know Newton’s 2nd law, which is:
