Question

5. Three point charges are inside a hole in a conducter. The conducter has a zero net charge.

(a) What is the total charge on the inside the surface of the conductor? Explain.

(b) What is the total charge on the outside the surface of the conductor? Explain.

(c) What is the total flux through a Gaussian surface below? (Answer in E0)

5. Three point charges are inside a hole in a conductor. The conductor has a zero net charge. (a) What is the total charge on the inside the surface of the conductor? Explain (b) What is the total charge on the outside the surface of the conductor? Explain. +q +7q -3q (c) What is the total flux through a Gaussian surface below ? (Answer in )

Explanation / Answer

5. (A) for Gaussian surface just outside the conductior surafce,

Qin = (-3q + q + 7q) + Q = 0

Q = - 5 q ,......Ans

(B) from Gauss law,

flux = Qin / e0 = (5q) / e0

Ans: 5 q / e0
