12th Class Physics Electrostatics & Capacitance Question Bank MCQ - Electrostatic Potential and Capacitance

  • question_answer
    A charge Q is placed at the origin. The electric potential due to this charge at a given point in space is V. The work done by an external force in bringing another charge q from infinity upto the point is:

    A) V/q                  

    B) Vq       

    C) V+q                            

    D) V

    Correct Answer: B

    Solution :

    (b) Vq Potential at a point in a field is defined as the amount of work done in bringing a unit positive test charge (q) from that point along any arbitrary path \[V=\frac{W}{{{q}_{0}}}\] \[\therefore \]Work done, W= qV
