The particle executing simple harmonic motion has kinetic energy K_(0)cos^(2)omegat. The maximum values of the potential energy and the total energy are respectively :

Answer»

`(K_(0))/(2)` and `K_(0)`
`K_(0)` and `2K_(0)`
`K_(0)` and `K_(0)`
0 and `2K_(0)`.

Solution :Kinetic energy `=K_(0)COS^(2)omega t`
When ` cos^(2)omega t=1`
thenkinetic energy `=K_(0)` (MAXIMUM).
Thus maximum value of potential energy `=K_(0)`
Maximum value of total energy
= maximumvalue of potential energy `=K_(0)`
Correct choice is ( C ).
