1-A piece of ebonite has a net charge of +7.20µC. How many more protons than electron does this piece of plastic have?
2-If particles A, B, and C, with charges -6.0 µC, 8.7 µC, and -5.4 µC respectively, are forcefully thrown together and then separate what is the net charge on particle B?
3- An proton is placed in a constant electric field of 8.16x104N/C.
4-What amount of work is required to bring a +3.1µC charge to within 5.0mm of an +2.7µC charge?
Ans 1: Since this is a positive charge it is made up of extra protons. The charge on each proton is equivalent to the charge on electron. Now from the quantization of charge, total charge = number of proton x charge on each proton
Thus, no of proton = total charge/charge on each proton
= = number of protons
Note: In Accordance with the Chegg policy if you ask more than one question in the single picture then only the first one will be answered.
