A charge Q is enclosed by a Gaussian spherical surface of radius R. If the radius is doubled, then the outward electric flux will
increase four times
be reduced to half
remain the same

Gauss's Law -
Total flux linked with a closed surface called Gaussian surface.
Formula:
- wherein
No need to be a real physical surface.
Qenc - charge enclosed by closed surface.
electric flux through a surface =
since is constant, flux will remain same.
Option 1)

Incorrect
Option 2)
be reduced to half
Option 3)
remain the same
Correct
Option 4)
be doubled
