A 1.25-kg book in space has a *weight* of 8.35 Newtons. What is the value of the gravitational field at that location?
Please help me with this problem.
I'm having trouble understanding how to find the answer.

Here on earth the book has a weight
W = m*g = 1.25 kg*9.8 m/s^2 = 12.25 N
In space
W = 8.35 N = m*a
a = 8.35 N/1.25 kg = 6.68 m/s^2
So the acceleration due to gravity at that point in space is 6.68 m/s^2.

Mass = 1.25kg
Force = 8.35N
Gravity= 9.8m/s2 (down)
GP= Mass * Gravity
= 1.25 * 9.8m/s2 (down)
= 12.25 N
Then....
Fnet = Mass * Acceleration
= 1.25kg * 20.6
= 25.75 N
If your wondering if how I got 20.6... Well, I added the force and the acceleration due to gravity.. Check the answer with someone....

Weight = mass * acceleration
