Question

The strength of an electric field depends on the

Answer 1

Electric field is directly proportional to the product of both the charges and inversely proportional to the square of distance between them. So, it depends on both, magnitude of charges, and the distance between them

In short, Your Answer would be Option D

Hope this helps!

Answer 2

Answer: The correct answer is " amount of charge on a test charge placed in the field."

Explanation:

The expression of the electric field at a distance from the source charge is as follows;

$E=\frac{kq}{r^{2} }$

Here, q is the charge, E is the electric field, k is constant and r is the distance from the charge.

The electric field and the distance have an inverse relation. It varies inversely as the square of the distance. The electric field is directly proportional to the charge.

The strength of the electric field increases with decrease in the distance from the charge. From the given options, the options (a) and (b) are correct. The electric field depends on the distance from the charge and the amount of charge that produces the electric field.

Therefore, the correct option is (d).
