A rectangular surface of side 10 cm and ...

A rectangular surface of side 10 cm and 15 cm is placed inside a unifrom electric field of `25 NC^(-1)`, such that normal to the surface makes an angle of `60^(@)` with the direction of electric field. Find the flux of electric field through the rectangylar surface.

Text Solution

Verified by Experts

Flux = E S `cos theta`
`=(25" N"//"C")(0.15xx0.10)m^(2)(cos 60^(@))`
`=0.1875" Nm"^(2)/"C"`
