In SHM restoring force is F=-k x , where k is force constant, x is displacement and A is amplitude of motion, then total energy depends upon
Options
- Ak, A and M
- Bk, x, M
- Ck, A
- Dk, x
Correct answer
C. k, A
Step-by-step solution
In SHM, the total energy Or array l = potential energy + kinetic energy E=U+K array aligned =& 1 2 m ² x²+ 1 2 m ² (A²-x² ) &= 1 2 m ² A²= 1 2 k A² where k= force constant =m ² aligned Thus, total energy depends on k and A .
