Albert needs to determine the force of gravity on a 250 g ball. the force of gravity on a 1000 g ball is about 10 newtons.
albert measures the force of gravity on the 250 g ball, and finds it to be 4 n. he does not think that this measurement is correct. what should be the force of gravity on the ball?

a.
the force of gravity on the ball should be 0 n.
b.
albert's measurements are correct.
c.
the force of gravity on the ball should be about 10 n.
d.
the force of gravity on the ball should be about 2.5 n.
