See the step by step solution

Step by Step Solution

Step 1 : Given information.

Free-fall acceleration is the acceleration experienced by a freely falling body towards a body with gravitational attraction.

Step 2 : Calculation (a).

The formula of free-fall acceleration is given by :

Known parameters:

Mass of sun:

Radius of sun

Distance from earth to sun:

Universal gravitation constant:

Step 3 : Continuation of calculation (a).

Therefore, the free-fall acceleration at the surface of Sun is :

Step 4 : Final answer (a).

The free-fall acceleration at the surface of the sun is

Step 5 : Calculation (b).

The free-fall acceleration at the surface of earth due to Sun is :

Step 6 : Final answer (b).

The free-fall acceleration at the surface of earth due to Sun is
