Question

A uniform electric field of magnitude E = 38 N/C points along the x-axis. A circular loop of radius R = 26 cm is centered at the origin with the normal to the loop pointing θ = 45 degrees above the x-axis.

Calculate the electric flux in units of N⋅m2/C that passes through the loop.

Answer 1

$\phi=EAcos\theta$

$=38×π×(26×10^{-2})^2cos45$

$=5.7064Nm^2/C$
