NEET Physics Time Period & Frequency MCQ Question
Type: MCQ-numerical-Hard-Class 11
If a block of mass 1 kg is attached to a spring with a spring constant of 50 N/m and is set into simple harmonic motion, what is the time period of its oscillation?
A
0.89 seconds
B
26 seconds
C
0.63 seconds
D
0.45 seconds
Correct Answer
Option A
Detailed Explanation
The time period T for a spring-block system is given by T = 2π√(m/k). Substituting m = 1 kg and k = 50 N/m, T = 2π√(1/50) = 0.89 seconds.
