Question

A circular disc with radius 0.1 m is kept in an electric field such that its normal makes an angle of 30 degree with a uniform electric field of magnitude 2KNC. What is the electric flux through the disc.

Answer 1

Explanation:

Here B=

π

1

(Wb/m²)

θ=60⁰

Area normal to the plane of the disc

= πr

2

(cos60⁰)=

2

πr

2

Flux = B x normal area

= 0.2×

2

0.2

=0.02Wb
