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
b. `vecE = 8hati + 4hatj + 3hatk, , vecA = 100hatk`
So `phi = vecE * vecA = 300 units`.
