JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors / वर्तमान बिजली, चार्ज और कैपेसिटर का निर Question Bank Assertion and Reason

  • question_answer
    Assertion             :       Electric field outside the conducting wire which carries a constant current is zero. Reason                 :   Net charge on conducting wire is zero.

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.
