Question

The energy of a simple harmonic oscillator in the state of rest is $3$ $Joules$. If its mean K.E. is $4$ $Joules$. Its total energy will be:

• A. $7$ $J$
• B. $8$ $J$
• C. $10$ $J$
• D. $11$ $J$

Answer 1

The correct option is A $7$ $J$

Total Energy $=$ Kinetic Energy $+$ Potential Energy

$\Rightarrow$ Total Energy $=(4+3)$ $J=7$ $J$
