  • question_answer
    if a square coil is making an angle \[60{}^\circ \] with electric field E according to figure the electric flux passing through the square coil is (the side of square is 4 cm):

    A)  853 E                                    

    B)  8 E

    C)  16 E                      

    D)         none of these

    Correct Answer: B

    Solution :

    The flux passing through the coil \[\Delta \phi =\vec{}\mathbf{.}\Delta \mathbf{\vec{S}}\] \[=E\Delta \,S\,\cos \,60{}^\circ \] \[\begin{align}   & =E\times (4\times 4)\times 12 \\  & =8E \\ \end{align}\]
