Gauss's Law: Practice Problem & Solution

A charge $Q$ is enclosed by a Gaussian spherical surface of radius $R$. If the radius is doubled, then the outward electric flux will: (2011 Pre)
Increase four times
Be reduced to half
Remain the same
Be doubled

Solution Explained:

To solve this problem, we apply the core principles of Gauss's Law. Understanding the underlying formula is key to arriving at the correct answer below:

According to Gauss's law, the total outward electric flux through any closed surface depends only on the net charge enclosed ($Q$). Since the enclosed charge remains the same when the radius is doubled, the flux will remain the same.
