Answer 2

5. one electron has charge -1.602 x 10^-19C

so you'd convert -30.0mC by dividing by 1000, then just divide by the charge per electron to get the # of electrons

Answer 3

6. a: the force that the second ion exerts on the first = the force that the first exerts on the second
6b: I'm not 100% sure on this one tbh but I think you would two ions exerting the same force on each other by drawing two equally sized arrows pointing from one ion to the other
6c: using coloumb's law

F = kqq/(r^2)
increasing the distance to 8r

F = kqq/(8r)^2, factor out the 8^2 from the denominator and you'll see that the force decreases by a scale factor of 1/64
