I was not pretty sure. Just wanted to confirm my answer. Sorry for multiple questions but my exam is after hours. I wish I have not broken the forum rules. ThanksHello Fatima,
PF is not intended for stamp-approvals. If you convince yourself that -9 nC is the right answer, then that IS your answer for this exercise !
And why shouldn't it be the right answer ?
You wrote that Q=1 nC and then that Q=-10+1 =-9 nC. These are wrong, although the answer "A" is correct. Pay more attention!
