Question
Answer the following with True or False
The total charge on the outer surface of the large shell is +2q.
The total charge on the inner surface of the large shell is -6q
The radial component of the electric field in the region r < a is given by -2q/(40r2).
The radial component of the electric field in the region r > d is given by +2q/(40r2).
The radial component of the electric field in the region c < r < d is given by +4q/(40r2).
The total charge on the outer surface of the small shell is -6q.
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 sh Net content recource charge of -2q and the outer shell has a total charge of +4q.Explanation / Answer
charge on inner surface of smaller shell=0
charge on outer surface of smaller shell=charge on the smaller shell=-2q
charge on inner surface of larger shell=-(-2*q)=2*q
charge on outer surface of larger shell=4*q-2*q=2*q
so answers are :
Q1. The total charge on the outer surface of the large shell is +2q.
the statement is TRUE.
Q2.The total charge on the inner surface of the large shell is -6q
the statement is FALSE.
Q3.The radial component of the electric field in the region r < a is given by -2q/(40r2).
the statement is FALSE.
reason: as per gauss' law, total electric flux passing thorugh a surface is equal to charge enclosed.
but for r<a, charge enclosed=0
hence electric field is 0.
Q4.The radial component of the electric field in the region r > d is given by +2q/(40r2)
the statement is TRUE.
total charge enclosed =-2*q+4*q=2*q
Q5.The radial component of the electric field in the region c < r < d is given by +4q/(40r2).
the statement is FALSE.
as total charge enclosed=-2*q+2*q=0
Q6. The total charge on the outer surface of the small shell is -6q.
the statement is FALSE.
Q7.The total charge on the inner surface of the small shell is -2q.
the statement is FALSE.
