If there is only one type of charge in the universe, then (E Electric field, ds Area vector)

JEE · NEET Previous Year Question

$If there is only one type of charge in the universe, then (E \to Electric field, d s \to Area vector)$

Topic: JEE PYQ

Answer: D. Full step-by-step solution below.

A $\oint E \cdot d s \neq = 0 on any surface$
B $\oint E \cdot d s could not be defined$
C $\oint E \cdot d s = \infty if charge is inside$
D $\oint E\cdotds=0 if charge is outside, = \frac{q}{ϵ _{0}} if charge is inside$

Correct answer: D

(d) If there is only one type of charge in the universe then it will produce electric field somehow. Hence Gauss's law is valid.
