Question
A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d. The inner shell has a total charge of -2q and the outer shell has a total charge of +3q.
Select True or False for the following statements.
1) The electric field in the region r < a is zero.
2) The radial component of the electric field in the region c < r < d is given by +3q/(4??0r2).
3)The total charge on the inner surface of the large shell is zero.
4)The electric field in the region r > d is zero.
5)The total charge on the inner surface of the small shell is -2q.
6)The total charge on the outer surface of the large shell is +1q.
7)The total charge on the outer surface of the small shell is -2q.
Use Gauss's Law.
Explanation / Answer
the factis that inside a conductor the electric field is zero
part 1 - true because net inclose charge is zero so by gauss law E is 0
2-false beacuse inside the cponducor eletric field is zero as i noted above
3-
4-false it exist and equal to +q/(40r2)
5-flase it is -q beacuse net charge is 3q-2q=q so let q is on center so -q will induced on inner surface to make elecric field zero beause lectric field doesnot exist inside
6-true
7-true
