In ordinary laboratory circuits, charges uC (microcoulomb) and nC (nanocoulomb) range are common. How many excess electrons must you add to an object to give it a charge of (a) -2.50 uC (b) -2.50 nC.

1. Divide both numbers by the electron charge (-1.6*10^-19 C) to get your answers.

Please show your work if you require further assistance. I will not be responding to any more of your questions unless work or some thought process is shown.

2. ok, well I would have some thought process if I had any idea how to do any of these! I am not asking for just the answer I am asking for some guidance on where to start just a little hint! physics is by far not one of my strong points.
