Electric flux will be maximum if the angle between the field lines and area vector is ______
A. 45 degree
B. 135 degree
C. 90 degree
D. 0 degree
Answer:D
Electric flux will be maximum if the angle between the field lines and area vector is ______
A. 45 degree B. 135 degree C. 90 degree D. 0 degree
Explanation: We know that the electric field and area both are vector quantity and the electric flux is expressed as \(\vec{E}.\vec{s}\) (taking dot product). But if the angle between the two vectors is θ then the formula becomes E.s.cosθ.Cosθ will be maximum if theta is zero, in all other cases, the value of Cosθ is less than 1. Therefore flux will be the maximum if the angle is 0 degrees.
