1.	A string of length l and mass m is fixed at both ends with tension t and excited in its fundamental mode.The maximum displacementat the mid point is A Find (a) the maximum kinetic energy of the string ,9b0 the mean kinetic energy of the srting averaged over one oscillation period hint Take sine distribution of amplitudes
Answer» Answer :`(1)/(2)mA^(2)omega^(2),(1)/(8)mA^(2)omega^(2)` where `omega=(PI)/(l)SQRT((T)/(m))`
