A point charge Q at the center of a sphere of radius R produces an electric flux of Φ coming out of the sphere. If the charge remains the same but the radius of the sphere is doubled, the electric flux coming out of it will be

Remains the same

Explanation:

According to Gauss's law, the electric flux through a closed surface is proportional to the charge enclosed by the surface. So no matter how big or small we make the surface that encloses the charge, the electric flux remains the same because it only depends on the enclosed charge, not surface area.
