MCQ
What type of surface is the surface of a conductor?
- ✓Equipotential
- BUnipolar
- CUnipotential
- DBipolar
✓
Answer
Correct option: A.
Equipotential
Electric field at any point is equal to the negative of the potential gradient. But inside a conductor, the electric field is zero. Hence, the electric potential is constant throughout the volume of a conductor and has the same value on its surface. Thus the surface of a conductor is equipotential.

Four bulbs, red, green, white and blue (denoted by $R$ $G, W$ and $B$ respectively) are kept in front of a converging lens (as shown in the figure below). The observer sees that the green and blue bulbs are kept to the left of the principal axis, while the red and white bulbs are kept to the right of the principal axis. He also sees that the red and green bulbs are above principal axis, while the white and blue bulbs are below the principal axis. The screens $S_1$ and $S_2$ are set appropriate positions for the focusing to view the images. Choose the figure that correctly represents the images as seen by the observer.
