Use Gausss law to obtain an expression for electric field due to an infinitely long Straight uniformly charged wire.
Electric field is directed along \( +x \) direction and given by \( E_{x}=5 A x+2 B \), where \( E \) is in \( \frac{N}{C} \), \( \& x \) is in metre \( A \) and \( B \) are Constants with dimensins.
Taking \( A=10 \mathrm{NC}^{-1} \mathrm{~m}^{-1} \) and \( B=5 \mathrm{NC}^{-1} \mathrm{~m}^{-1} \) calculate:
(1) Electric flux through the cube.
(2) Net charge enclosed with in the cube
