Comments four point charges of magnitude 3. 5 mu or micro cc are at the corners of a square of side 6 m. (a) find the electrostatic potential energy if all of the charges are negative.

b) well because you get well

its 4 because 2 times 2 is 4, if you double the number two you get four

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
