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

  • question_answer
    Two plates have net charge 70 pC and -70 pC connected to a potential of 20 V, the capacitance of the system is:

    A) 3.5pF   

    B) 7pF      

    C) 7 pC                            

    D) 10.5 pF

    Correct Answer: A

    Solution :

    (a) 3.5pF    Capacitance is given by, \[C=\frac{q}{V}=\frac{70}{20}=3.5\,pF\]
