JEE Main & Advanced Physics Work, Energy, Power & Collision / कार्य, ऊर्जा और शक्ति Question Bank Self Evaluation Test - Work, Energy and Power

  • question_answer
    A body of mass 10 kg moves with a velocity v of 2m/s along a circular path of radius 8 m. The power produced by the body will be

    A) 10J/s

    B) 98J/s

    C) 49J/s

    D) zero

    Correct Answer: D

    Solution :

    [d] The power of body is given by \[= \vec{F}.\vec{V}\]as the body is moving in circular path, centripetal force and velocity are at\[90{}^\circ \], or power =0.
