  • question_answer
    Two thin dielectric slabs of dielectric constants \[{{K}_{1}}\] and \[{{K}_{2}}\]\[({{K}_{1}}<{{K}_{2}})\] are inserted between plates of a parallel plate capacitor, as shown in the figure. The variation of electric field 'E' between the plates with distance 'd' as measured from plate P is correctly shown by:

    A)

    B)       

    C)   

    D)

    Correct Answer: C

    Solution :

    Electric field, \[E\propto \frac{1}{K}\] As \[{{K}_{1}}<{{K}_{2}}\] so \[{{E}_{1}}>{{E}_{2}}\] Hence graph correctly dipicts the variation of electric field E with distance d.
