Question

Which factor indicates the amount of charge on the source charge?

Answer 1

Answer:

B. the number of field lines on the source charge

Explanation:

As we know that electric flux is defined as the number of electric field lines passing through a given area.

So here  electric flux due to a point charge "q" is given by

$\phi = \frac{q}{\epsilon_0}$

so here we know that flux depends on the magnitude of charge and hence we can say that number of filed lines originating from a point charge will depends on the magnitude of the charge.

so here correct answer will be

B.   the number of field lines on the source charge

Answer 2

B. The number of field lines on the source charge.
