Question

The particle executing SHM has a kinetic energy Kcos^2wt. The maximum values of the potential energy and the total energy are respectively

1- k/2 and k 2- k and 2k

3-k and k 4- 0 and 2k

Answer 1

Answer: 3

Explanation:

Remember the energy curve for shm. The value of max energy are same.

TE= KE+PE

when particle is at mean position

Ke= k. Pe=0 TE =k

When particle is at extreme position

Ke=0 Pe= k Te=k

Answer 2

Explanation:

K.E+P.E-T.E WHEN when kinetic energy is Maximus p.e is 0
