Question

Select the correct graph showing the difference (d) between total energy and potential energy of a particle in linear SHM with position x of the particle (x = 0 is the mean position)

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

The correct option is (A):

d=T.E-P.E

=K.E($\because$ the total energy is conserved)

$=\frac{1}{2}m\omega^2(A^2-x^2)$
