Recall that Coulomb's constant is ke-8.99-10°Nm²/C2. Two identical charged objects are placed 1.00m apart from each other and an electrostatic force of Fe = 3.00N is measured between them. What is the charge, 9, on each object?
Your

v=ir = 3x15 =45 v

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
