Consider a uniform eleceric field `=3 xx 10^(3) hati N//C.`
a. What is the flux of this field through a square of 10cm on a slide whose plane is parallel to the yz plane?
b. What is the flux through the same square if the moral to its plane makes a `60^@` and with the satis?

Text Solution

`E=3 xx 10^(3) NC^(-1), r=10 xx 10^(-2) m`
`phi=E xx " Area "=3 xx 10^(3) xx (10 xx 10^(-2))^(2) =30Nm^(2) C^(-1)`
b. `phi =E xx "Area " xx cos 60^(@)=30 xx 1/2 =1.5 Nm^(2)C^(-1)`
