A string with tension T and mass per unit length `mu` is clamped down at x=0 and at x=L. at t=0, the string is at rest and displaced in the y-direction `y(x,0)=2"sin"(2pix)/(L)+2"sin"(pix)/(L)` Q. At what time t will the string for the first time have exactly the same shape as it did at time t=0?A. `(L)/(2v)`B. `(L)/(v)`C. `(2L)/(v)`D. `(3L)/(v)` |
