There exists an electric field of 100 N/C along Z-direction. The flux passing through a square of 10 cm sides placed on XY plane inside the electric field is.......

Answer»

`1.0 Nm^(2)//C`
2.0 Vm
10 Vm
`4.0 Nm^(2)//C`

Solution :`E = 100 hatk N//C, l = 10 cm = 0.1 m, hatk` is for Z-axis.
`A = 0.1 xx 0.1 = 0.01 m^(2)hatk (therefore A =l^(2))`

FLUX, `phi = vecE.vecA= 100 xx 0.1 xx hatk.hatk`
`therefore phi =1 Nm^(2)//C`
