Given:
A satellite is orbiting around the earth at a distance 5 times the radius of the earth from its centre.
To find:
Gravitational acceleration on the spaceship?
Calculation:
General expression for gravitational acceleration at a height h from earth surface:
Now, height from centre of earth = 5r, so height from earth surface is :
Now, continuing with the calculations:
So, gravitational acceleration on spaceship is 0.392 m/s².
