In a region of space, the electric field is given by `vecE = 8hati + 4hatj + 3hatk`. The electric flux through a surface of area 100 units in the xy plane is

A

800 units

B

300 units

C

400 units

D

1500 units

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `E=8hati+4hatj+3hatk`
`S=100hatk`
(Direction of area is perpendicular to xy-plane)
`phi=E.S=(8hati+4hatj+3hatk).100 hatk`
= 300 units
