Question

A solid cone of base radius equal to $R$ and height equal to $H,$ is placed in a uniform electric field of magnitude $E$ and directed parallel to the axis of the cone. Net electric flux through the cone would be equal to

$[$0.77 Mark$]$

• A. Zero
• B. $E\pi R^2$
• C. $2E\pi R^2$
• D. $3E\pi R^2$

Answer 1

The correct option is A Zero

As in the given case, the number of field lines entering the cone is equal to field lines leaving the cone. So net flux is zero.
