Question 1
1 / -0

A point charge causes an electric flux of −1.0 × 10³Nm²/C to pass through a spherical Gaussian surface of 10.0 cm radius centred on the charge. If the radius of the Gaussian surface were doubled, how much flux would pass through the surface?

A
−10³Nm²/C

B
−10²Nm²/C

C
10⁴Nm²/C

D
10³Nm²/C

Solution

Electric flux is given by ϕ = q/∈₀ since amount of charge not depends on size and shape so by making radius double the amount of charge remain same, so electric flux remain same.
