SHMHard
Question
A particle of mass m executing SHM makes f oscillation per second. The difference of its kinetic energy when at the centre and when at a distance x from the centre is
Options
A.π2f2x2m
B.2π2f2x2m
C.
π2f2x2m
π2f2x2mD.f2x2m
Solution
KE at centre
=
mω2(A2) = m4π2f2A2
KE at distance x
=m4π2f2(A2 - x2)
Difference = m × 4π2f2x2 = 2π2f2x2m
=
mω2(A2) = m4π2f2A2KE at distance x
=
m4π2f2(A2 - x2)Difference =
m × 4π2f2x2 = 2π2f2x2mCreate a free account to view solution
