  • question_answer
    A string of 7 m length has a mass of 0.035 kg. If tension in the string is 60.5 N, then speed of a wave on the string is [CBSE PMT 2001]

    A)            77 m/s                                    

    B)            102 m/s

    C)            110 m/s                                  

    D)            165 m/s

    Correct Answer: C

    Solution :

                 \[v=\sqrt{\frac{T}{m}}\] Þ \[v=\sqrt{\frac{60.5}{(0.035/7)}}=110\]\[m/s\]
