Question

Sapling Learning earning A positive point charge is placed at the center of an imaginary spherical surface. As a result, there is some total electric flux outward through the surface. For each of the changes listed below, how would the total outward flux though the surface change? The total flux increases The total flux decreases The total flux is unchanged a nega just outside the surface surface is doubledby an amount equal to half the erical surface a negative charge is placed a positive charge is placed a positive charge is placed Previous

Explanation / Answer

from the Gauss law , the total electric flux through a closed surface is equal to 1/ eo times of total charge enclosed in the surface.

flux = q_ enclosed / eo

(a)

if we want to increase flux ,we must place a positive charge is inside the surface

(b)

if we want to decrease flux ,we must place  a negative charge is inside the surface

(c)

the options

a positive charge is placed just outside the surface

a negative charge is placed just outside the surface

the charge is moved off- centerby an amount of equal to the half radius of the spherical surface

the radisu of spherical surface is doubled

all above options does not change the flux
