535055 22.3 Problem 22.3-Enhanced-with Feedback Part A A plastic rod that has beon charged to-15 nC touches a metal sphere. Afterward, the rod's charge is -90 nC What kind of charged particle was transferred beteeen the rod and the sphere, and in which drection? That is, did ia move from the rod to or from the sphere to the rod? O electrons, from the rod to the sphere electrons, trom the sphere to the rod e protons, from the rod to the sphere protons, torn the sphere tothe rod Part B How many charged particles were transterred? -? particles N 37453.18352Explanation / Answer
Part A : electrons from the rod to sphere
partB:
Charge flowed = -15 + 9 = -6 nC
We dont consider sign for convenience
1 particle makes up 1.6*10^-19 C charge
6*10-9 nc charges make =
6*10^-9/1.6*10^-19 = 3.75*1010 ---->Ans
