i'm studying for my SAT II Physics on June 7, 2008. and taking practice tests from REA.
i had trouble understanding this question. please help :) it would be VERY appreciated.
Two charges are separated by 2 m. The force of attraction between them is 4 N. If the distance between them is doubled, the new force between them is...
A) .5 N
B) 1 N
C) 2 N
D) 4 N
E) 8 N
Force = [K(Q1)(Q2)] / (R^2)
the formula is on http://www.sparknotes.com/testprep/books/sat2/physics/chapter13section2.rhtml under Coulomb's Law
i'm sorry, i really couldn't figure out. it's probably a simple question, and i just can't see it.
PLEASE HELP!
thank you SO much
