PLEASE EXPLAIN IN GREAT DETAIL WITH FORMULAS SO THAT I CAN DO SIMILAR PROBLEMS

3. A fully-charged 0.01 F capacitor has an electric potential difference between its plates of 9.0 V. What is the magnitude of charge Q on one plate of the capacitor?
A.0.09 C
B.0.18 C
C.0.27 C
D.0.36 C
E.0.11 C

15. A PVC (plastic) rod and piece of fur are initially neutral. In class, the instructor rubs the rod with the piece of fur and the rod obtains a charge of -14 nC . What charge does the fur obtain?
A.14 nC
B.-14 nC
C.0 nC
D.7 nC
E.-7 nC

Explanation / Answer

15 ) 14nC electrons from rod go onto the rod and hence it obtained negative charge . hence fur obtains positive charge of 14nC

3) C= Q/V

Q= C*V

= 0.01*9

= 0.09C
