NEET 2021 Physics Simple Harmonic Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
A spring is stretched by 5 cm by a force 10 N. The time period of the oscillations when a mass of 2 kg is suspended by it is :
A
0.0628 s
B
6.28 s
C
3.14 s
D
0.628 s
Correct Answer
Option D
Detailed Explanation
Use Hooke's law to find the spring constant, then apply the formula for the time period of a mass-spring system: T = 2π√(m/k).
