Electric flux through a surface of area ...

Electric flux through a surface of area `100 m^(2)` lying in the plane in the xy plane is (in V-m) if `E=hat(i)sqrt(2)hat(j)+sqrt(3)hat(k)`:

A

100

B

141.4

C

173.2

D

200

Text Solution

Verified by Experts

The correct Answer is:
C
Area `(100 m^(2))` in xy plane so area vector in `hatk`
`=int vec(E)_(z).dvec(S)=sqrt(3)hat(k).100 hat(k)=173.2`
`=int vec(E)_(z).dvec(S)=sqrt(3)hat(k).100 hat(k)=173.2`
