MCQ
Electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius $10\ cm$ surrounding the total charge is $25V-m.$ The flux over a concentric sphere of radius $20\ cm$ will be:
  • $25V-m$
  • B
    $50V-m$
  • C
    $100V-m$
  • D
    $200V-m$

Answer

Correct option: A.
$25V-m$
$F$ is not depend on the shape $\&$ size of the closed volume surface.
$q_m\ Þ\ q_m$ is the net charge inside the closed volume surface.
