A uniform electric field of magnitude E=...

A uniform electric field of magnitude `E= 100 N C^(-1)` exists in the space in x-direction. Calculate the flux of this field through a plane square of edga 10 cm placed in the y-z plane. Take the normal along the positive x-axis to be positive.

Text Solution

Verified by Experts

The Flux `Phi = int E cos theta dS`. As the normal to the area point along the electric field, `theta = 0` . Also, `E` is unifrom, so
`Phi = E Delta S`
`=(100 NC^(-1)) (0.10m)^(2) = 1.0 Nm^(2)C^(-1)`.
