A long strikes with a charge of `lambda` per unit length passes through an imaginary cube of edge `a`. The maximum flux of the electric field through the cube will be

Options

A. `(lambda a)/(epsilon_(0))`
B. `sqrt((lambda a)/(epsilon_(0)))`
C. `(6 lambda a^(2))/(epsilon_(0))`
D. `(sqrt(3) lambda a)/(epsilon_(0))`

Answer

4

Explanation

The length of diagonal `= sqrt(3) a`
`phi_(max) = (q_(in))/(in_(0)) = (sqrt(3) lambda a)/(in_(0))`
