Question

Frequency of a block in spring-mass system is $\upsilon$, if it is taken in a lift slowly accelerating upward, then frequency will

• A. decrease
• B. increase
• C. remain constant
• D. none

Answer 1

The correct option is C remain constant

$\omega =2\pi \sqrt{\frac{K}{M}}$

Frequency is independent of gravity

Hence it will remain constant
