# Gravitational acceleration on Planet Deneb

Not what you're looking for?

We call the acceleration due to gravity on the Earth's surface "g". The planet Deneb Prime has a mass of 280 times that of Earth and a radius of 6 times that of Earth. Compared to Earth, what is the acceleration due to gravity on Deneb Prime? Express your answer in g's. So if you compute a value for the gravitational acceleration on Deneb Prime of, for example, 3.2g, you should simply enter "3.2".

##### Solution Summary

The solution calculates gravitational acceleration on Planet Deneb.

F = ( G M m) / r 2
F= mg
Or mg= ( G M m) / r 2
Or g= (G M) / r 2

G= Universal ...
