## Homework Statement

What is the gravitational force between Earth and the sun if the Earth has a mass of 5.98 x 10^24 and the sun has a mass of 1.99 x 10^30. The r is (1.5 x 10^11)^2[/B]

## Homework Equations

F=(Gm

_{1}m

_{2})/r^2

G= 6.67 x 10^-11 N m^2 /kg^2 ( note that this is a constant)[/B]

## The Attempt at a Solution

I simply plugged in, and gathered the like terms and put them together accordingly so i got [( 6.67)(5.98)(1.99)]/(1.5)^2=35.277 ... Then you would move the decimal to get 3.52[/B]

**Next i got all the exponent so( i canceled out the ten) -11+30+24-22= 21**

**so I got 3.52 x 10^21 N but the answer key said it is 3.52 x 10^22 N**

**What did I miss or is it a typo?**
