Question

Electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius $10\text{cm}$ containing the total charge is $25\text{V-m}$. The flux through a concentric sphere of radius $20\text{cm}$ will be?

• A. 25 V-m
• B. 50 V-m
• C. 100 V-m
• D. 200 V-m

Answer 1

The correct option is A

25 V-m

As the net charge enclosed for both spherical surfaces remains the same, flux remains the same.
