Two independent harmonic oscillators of equal mass are oscillating about the origin with angular frequencies ω1 and ω2 and have total energies E1 and E2 , respectively. The variations of their momenta p with positions x are shown in the figures. If ab=n2 and aR=n , then the correct equation(s) is (are)

  1. E1ω1=E2ω2
  2. ω2ω1=n2
  3. ω1ω2=n2
  4. E1ω1=E2ω2

Solution

P1 max=maω1=b
P2 max=mrω2=R
ω1ω2=1n2
ω2ω1=n2
E1=12mω12a2
E2=12mω22R2
E1E2=ω12ω22a2R2=ω12ω22n2=ω12ω22ω2ω1
E1E2=ω1ω2
E1ω1=E2ω2 .
