What is its time period? A) 0.1 s B) 0.2 s C) 1 s D) 10 s 2 / 5 Q.2 The time period of a simple pendulum is given by the formula T = 2π √(l/g), where l is the length of the pendulum and g is the acceleration due to gravity. If the length of the pendulum is doubled, its time period becomes: A) √2 times B) 2 times C) 1/√2 times D) 1/2 times 3 / 5 Q.3 The displacement of a particle executing simple harmonic motion is given by the equation y = A sin (ωt + φ), where A is the amplitude, ω is the angular frequency and φ is the phase constant. If the amplitude is doubled, the maximum velocity of the particle becomes: A) √2 times B) 2 times C) 1/√2 times D) 1/2 times 4 / 5 Q.4 The frequency of oscillation of a mass-spring system is given by the formula f = 1/(2π) √(k/m), where k is the spring constant and m is the mass attached to the spring. If the spring constant is halved, the new frequency of oscillation becomes: A) 2 times B) √2 times C) 1/2 times D) 1/√2 times 5 / 5 Q.5 Two simple pendulums have time periods T1 and T2. If their lengths are in the ratio of 3:4, then what is the ratio of their frequencies of oscillation? A) 3:4 B) 4:3 C) 9:16 D) 16:9 Your score is The average score is 54% LinkedIn Facebook Twitter VKontakte 0% Restart quiz
