  1. Question 1

    Q1. A spring-mass system has a time period T. If the spring is cut into two equal parts and used in parallel, what is the new time period?

    • A) T/2
    • B) T
    • C) 2T
    • D) T/√2

    Answer: T/2

    Explanation: k_eff = 2k + 2k = 4k. T ∝ 1/√k, so T_new = T/√4 = T/2.
