RAJASTHAN PMT Rajasthan - PMT Solved Paper-2010

  • question_answer
    The potential at a point due to an electron dipole will be maximum and minimum when the angles between the axis of the dipole and the line joining the point to the dipole are respectively

    A) \[90{}^\circ \text{ }and\text{ }180{}^\circ \]        

    B) \[0{}^\circ \text{ }and\text{ }90{}^\circ \]

    C) \[90{}^\circ \text{ }and\text{ }0{}^\circ \]

    D)        \[0{}^\circ \text{ }and\text{ }180{}^\circ \]

    Correct Answer: D

    Solution :

    Potential\[V=\frac{p\cos \theta }{{{r}^{2}}}\] If\[\theta ={{0}^{o}}\]then\[{{V}_{a}}=\]maximum If\[\theta ={{180}^{o}}\]then\[{{V}_{e}}=\]minimum
