Okay, so I have this physics problem that I can't quite lay my finger on, and it includes nanoCoulombs. Usually when we do problems like this we use microCoulombs which is # x 10^ -6. But our instructor did not tell us what nanoCoulmbs is, would it be # x 10^ -8?
BTW. The question is..
Two point charges of magnitude 9nC and -2 nC are separated by 31.5cm. The Coulomb constant is 8.99755 x 10^9 Nm^2/C^2.
What is the potential difference between a point infinitely far away and a point midway between the charges? Answer in units of V.
If you can't solve it, knowing the scientific notation of nC would be VERY helpful.
Thank you. :]

A nC = 10^-9 C or 10^-3 uC.
milli = 10^-3, micro = 10^-6, nano = 10^-9, pico = 10^-12, femto = 10^-15, alto = 10^-18....BTW a picoFarad is commonly called a puff.
The answer is that from infinitely far away the two charges essentially merges and yield a 7nC charge

steer away from employing "x" for multiplication. It gets at a loss for words with the variable. (4*10^3)(2*10^4) employing the associative and commutative rules of multiplication, 4*2*10^3*10^4 8*10^(3+4) 8*10^7

It is 10 ^ -9.
And I'll leave the solving part to you. Hehehe.
