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

  • question_answer
    Two plates are at potentials ?10 V and +30 V. If the separation between the plates be 2 cm. The electric field between them is                                                       [Pb. PET 2000]

    A)            2000 V/m

    B)            1000 V/m

    C)                    500 V/m

    D)                                     3000 V/m

    Correct Answer: A

    Solution :

                 \[E=\frac{V}{d}=\frac{30-(\,-\,10)}{(2\times {{10}^{-2}})}=2000\,V/m.\]
