Question

A particle executes SHM with a frequency $f$. The frequency with which its KE oscillates is

• A. $\frac{f}{2}$
  
• B. $f$
  
• C. $2f$
  
• D. $4f$
  

Answer 1

The correct option is C $2f$

If we consider the motion of a particle performing SHM the velocity attains its maxima and minima twice in an oscillation.

As frequency is defined as the number of cycles per second. Hence, it will be two times the original frequency of SHM.
