The meaning of u (Mu)?

[ND3G]

You are observing the effects of a single point charge with a magnitude of +4.3uC

Calculate the strength of the electric field 3 cm away from the charge (in any direction

I am curious as to the meaning of u (mu) in the above question. I am sure they would not have included it arbitrary but I am not aware of its value in this case.

It stands for "micro", which is 10^(-6).

The unit here is micro-coulomb (mu being the prefix for micro). One micro-coulomb has the value of 10^-6 coulombs
