NEET Physics Electric Potential MCQ Question
Consider a diagram showing a uniform electric field across a dielectric slab with the field lines running from left to right. Which of the following correctly describes the charge distribution at the surfaces of the slab?
Positive charges accumulate on the right surface and negative charges on the left surface.
Negative charges accumulate on the right surface and positive charges on the left surface.
There is no charge accumulation on either surface.
Both surfaces have a uniform distribution of positive charges.
Correct Answer
Detailed Explanation
In a dielectric placed in a uniform electric field, the positive ends of the dipoles are unneutralised at the right surface and the negative ends at the left surface, resulting in induced charges due to the external field.
