Question

A thin infinite sheet charge and an infinite line charge of respective charge densities +σ and +λ are placed parallel at 5 m distance from each other. Points ‘P’ and ‘Q’ are at $\frac{3}{π}$m and $\frac{4}{π}$ m perpendicular distance from line charge towards sheet charge, respectively. ‘EP’ and ‘EQ’ are the magnitudes of resultant electric field intensities at point ‘P’ and ‘Q’, respectively. If $\frac{E_p}{E_Q} =\frac{ 4}{a}$ for 2|σ| = |λ|. Then the value of a is _______.

Answer 1

The correct answer is: 6
