## Homework Statement

Find the gravitational force of the sun on Mercury

M_sun = 1.98892 x10^30 kg

M_mercury = 3.3022 x10^23 kg

Distance of sun and mercury = R = 6.863 x10^10

G = 6.67 x10^-11

## Homework Equations

F

_{G}= GM

_{sun}M

_{mercury}/R^2

## The Attempt at a Solution

I simply plugged in the given values (which I found from wolfram alpha) into the formula for F_G and I calculated the answer to be:

9.300 x10^21 N

However, the answer is not correct. If anyone can correct my mistake, that would be greatly appreciated.

Thanks
