Important Questions For Class 12 Physics 

Here are some important questions about physics that will help you in your preparations:

Question 1:

For a Gaussian surface through which the net flux is zero, the following statements COULD be true.

P) No charges are inside the Gaussian surface.

Q) The net charge inside the surface is zero.

R) The electric field is zero everywhere on the surface.

S) The number of field lines entering is equal to the number of lines exiting the surface.

Which of the statements is/are DEFINITELY true?

A. Only statement Q

B. Both statements P and S

C. Both statements Q and R

D. Both statements Q and S

Derive the expression for the electric field produced by a dipole at a point on the axis of the dipole.

Question 2:

‍Two positive charges q1 and q2 lie along a straight line separated by a distance of 2 m as shown.

(a) Find a location along the straight line joining the two charges, where if a positive charge q3 is placed, it experiences a zero-resultant force.

(b) Will the resultant force on q3 placed at the location of the part (a) still be zero, if Is it negatively charged? Explain.

Question 3:

The electric field inside a hollow conductor placed in an external electric field is always zero as shown in the figure. This property of a conductor finds a very useful application in shielding sensitive electric equipment. Electric circuits are enclosed within metal boxes that provide shielding from external fields, thereby protecting them from external interferences.

Given here is a hollow, electrically neutral spherical conductor. A positive charge q is suspended at its center.

Explain with an appropriate reason if this hollow conductor shields the OUTSIDE from the field produced by the point charge inside. Represent the electric field lines diagrammatically.
