JEE Main & Advanced Physics Work, Energy, Power & Collision / कार्य, ऊर्जा और शक्ति Question Bank Elastic and Inelastic Collision

  • question_answer
    Two perfectly elastic particles P and Q of equal mass travelling along the line joining them with velocities 15 m/sec and 10 m/sec. After collision, their velocities respectively (in m/sec) will be     [CPMT 1988; MP PMT 1994]

    A)          0, 25                             

    B)          5, 20

    C)          10, 15                           

    D)          20, 5

    Correct Answer: C

    Solution :

             For a collision between two identical perfectly elastic particles of equal mass, velocities after collision get interchanged.
