Questions  

Two simple harmonic motions are represented by the equations y1=0⋅1sin⁡100πt+π3 and y2=0⋅1cos⁡(100πt) The phase difference of the velocity of particle 1 with respect to the velocity of particle 2 is

a
π/6
b
π/3
c
−π/6
d
−π/3

detailed solution

Correct option is C

From the given eqs. dy1dt=v1=0⋅1×100πcos⁡100πt+π3Similarly v2 = dy2dt = -0.1×100π sin 100πt = 0.1×100π cos (100πt +π2)Therefore â–³Ï† = Ï€3-π2 = -π6
