Question

A charge Q µc is placed at the centre of cube, the flux coming out from any surfaces will be : -

• A. \(\frac{Q}{6\epsilon_0}\times 10^{-6}\)
• B. \(\frac{Q}{6\epsilon_0}\times 10^{-3}\)
• C. \(\frac{Q}{2\epsilon_0}\)
• D. \(\frac{Q}{8\epsilon_0}\)

Answer 1

The Correct Option is A

The correct option is (A): \(\frac{Q}{6\epsilon_0}\times 10^{-6}\)
flux coming out =\(\frac{Q_{enclosed}}{\epsilon_0}\).
E.ds=\(\frac{Q\times 10^{-6}}{\epsilon_0}\)(guass law)
=flux by one of the side = \(\frac{Q\times 10^{-6}}{6\epsilon_0}\)
= \(\frac{Q\times 10^{-6}}{6\epsilon_0}\)
