Answer:
The flux will be nine times as great.
Explanation:
The electric flux due to a charge Q located in the center of a sphere can be obtained using Gauss's law. Considering a Gaussian surface in the form of a sphere of radius r:
The electric field (E) is parallel to the surface vector (dS), so
Since the electric flux is proportional to the square of the sphere's radius, if radius of sphere were tripled, the flux will be nine times as great.
