JEE Main & Advanced Physics Electrostatics & Capacitance Question Bank Electric Field and Potential

  • question_answer
    At a certain distance from a point charge the electric field is \[500\,V/m\] and the potential is \[3000\,V\]. What is this distance  [MP PMT 1995; Pb. PMT 2001; AFMC 2001]

    A)                                                               \[6\,m\]

    B)                                              \[12\,m\]

    C)                                                               \[36\,m\]

    D)                                              \[144\,m\]

    Correct Answer: A

    Solution :

                         \[V=E\times \,r\] Þ \[r=\frac{V}{E}=\frac{3000}{500}=6\,m\]
