A)
B)
C)
D)
Correct Answer: B
Solution :
(b) |
Time taken to reach the extreme position from equilibrium position is\[\frac{T}{4}\]. Velocity is maximum at equilibrium position and zero at extreme position. |
\[V=A\,\omega \,\cos \omega t\] |
\[K.E=\frac{1}{2}m{{v}^{2}}\] |
(m is the mass of particle and v is the velocity of particle |
\[K.E=\frac{1}{2}m{{A}^{2}}{{\omega }^{2}}{{\cos }^{2}}\omega t\] |
Hence graph of K.E. v/s time is square cos function |
