Reverse Bias

Q. The conducting shells A AND B are arranged as shown below . if charge on the shell B is q then electric flux linked with the spherical gaussian surface S is

Q. A closed solid conductor of irregular shape is given some charge. Which of the following statement is correct? Options: Potential of conductor will change if its shape is changed Electric field inside it is non-zero All points on its surface will have same-charge density All of these

Q. An isolated conductor of any shape has a net charge of +10micro coulomb. Inside the conductor is a cavity within which is a point charge of +3micro coulomb. What is the charge on the cavity wall? On the outer surface of the conductor.

Q.

The reverse biasing in a PN junction diode

1. Decreases the potential barrier

2. Increases the potential barrier

3. Increases the number of minority charge carriers

4. Increases the number of majority charge carriers

Q. Why charge is not relativistic

Q. separation between the charges is r points A is at distance r from -q B is at a distance of r from +q charge and c is the distance mid point find the net electric field A, B, C

Q. Six equal resistances are connected between points P, Q and R as shown in the figure. Then the net resistance will be maximum between

1. P and Q
2. Q and R
3. P and R
4. any two points

Q. When we put a charge inside hollow metallic shell we say that the electric field is not zero as the gaussian surface is drawn just including charge kept but if we talk about whole shell from inside we can see that the sum of the charge kept inside the shell and induced charge on inner surface of shell due to that charge kept is zero so which case to consider when it is asked whether electric field is zero or not inside the shell ? And also is net electric field different from just electric field
