    Answer:

    Explanation:

    Electric field between plates of a parallel plate capacitor is uniform .

    In a uniform electric field , relation between electric field and potential gradient is as follows

    electric field = potential gradient               [ E = – dV / dl ]

    in the given case ,

    dV = 51 V  ,

    dl = 4 cm

    =  4 x 10⁻² m

    E = 51 /  4 x 10⁻²

    = 12.75 x 10² V / m

    = 1275 V / m
