Homework Help: Electrical versus Gravitational Forces (Physics)

Posted by Angela on Friday, February 25, 2011 at 2:35pm.

Multiple Choice help:

* _____ forces between charges are enormous in comparison to ______ forces. *

A. electrical, gravitational (possible?)
B. gravitational, electrical (possible?)
C. positive, negative (wrong, I think)
D. negative, positive (wrong, I think)

According to the review sheet, even a small charge of 10 x 10^-9 (or .0000000001) can result in large forces.

Please explain what that statement would mean for the multiple choice review. I think that the answer should be A according to the statement from the review sheet. Additionally, I think that both C and D can be ruled out as wrong.
