MCQ
A spring mass system preforms $S.H.M.$ If the mass is doubled keeping amplitude same, then the total energy of $S.H.M.$ will become :
- Adouble
- Bhalf
- ✓unchanged
- D$4$ times
✓
Answer
Correct option: C.
unchanged
c
The total energy of the mass spring system is equal to $\frac{1}{2} k A^{2},$ which is independent of mass. So the total energy will remain unchanged if amplitude is kept the same.
