12th Class Physics Electric Charges and Fields Question Bank Case Based (MCQs) - Electric Charges and Fields

  • question_answer
    The electric field within the nucleus is generally observed to be linearly dependent on r. So,

    A) \[a=0\]

    B) \[a=\frac{R}{2}\]

    C) \[a=R\]

    D) \[a=\frac{2R}{3}\]

    Correct Answer: C

    Solution :

    For uniformly volume charge density, \[E=\frac{\rho r}{3{{\varepsilon }_{0}}}\] \[E\propto r\]
