NEET AIPMT SOLVED PAPER MAINS 2010

  • question_answer
    A particle of mass M starting from rest undergoes uniform acceleration. If the speed acquired in time T is v, the power delivered to the particle is                                                          

    A) \[\frac{M{{v}^{2}}}{T}\]

    B) \[\frac{1}{2}\frac{M{{v}^{2}}}{{{T}^{2}}}\]           

    C) \[\frac{M{{v}^{2}}}{{{T}^{2}}}\]

    D) \[\frac{1}{2}\frac{M{{v}^{2}}}{T}\]

    Correct Answer: D

    Solution :

    The kinetic energy of particle\[=\frac{1}{2}M{{v}^{2}}\] \[\text{Power}\,\text{=}\frac{\text{Energy}}{\text{Time}}\] \[P=\frac{1}{2}\frac{M{{v}^{2}}}{T}\]
