A 100 Hz sinusoidal wave is travelling in the positve x – direaction along a string with a linear mass density of `3.5 xx10^(-3) kgm ^(-1)` and a tension of 35 N. At time t =0 ,the point x=0 has zero displacment and the slope of the string is `pi//20`then select the wrong alternative.
A. velcoity of wave is 100 m/s
B. angular velocity is `(200 pi)` rad /s
C. Amplitude of wave is 0.025 m
D. none of the above
