Question

(a) The electric field in a certain region is E (4.0)) N/C. Determine the electric flux due to this freld through an area represented by the vector A (1.51-7.k) m 29 How is the flux defined in terms of the electric field vector, and the area vector?

Answer 1

(a) electric flux = E.A

= (-4j) . (1.5i - 7.3k)

= 0

(b) E.A

= (-4j).(1.5i - 7.3j)

= (-4)(-7.3) = 29.2 Nm^2/C
