The electric field in the region of the space is vecE = (5hati + 2hatj + 3hatk)NC^(-1). The electric flux passing through a surface of area 50m^2 placed in X-Y plane inside the electric field is.......

Answer»

250 `Nm^(2)C^(-1)`
`150 Nm^(2)C^(-1)`
`100 Nm^(2)C^(-1)`
`200 Nm^(2)C^(-1)`

Solution :Here, `VECA = (50 hatk)m^(2)` and `vecE = (5hati + 2hatj + 3hatk)NC^(-1)`
`therefore phi=vecE.vecA`
`=(5hati + 2hatj + 3hatk).50hatk =150 Nm^(2)C^(-1)`
