The correct Answer is:
A
At `t=1 sec, s_1=vt=10xx1=10cm`
`t=2sec, s_2=vt=10xx2=20cm`
`t=3sec, s_3=vt=10xx3=30cm`

Two triangular wave pulses are travelling toward each other on a stretched string as shown in Fig . 7.25. Both pulses are identical to each other and travels at 2.00 cm//s . The leading edges of the pulses are 1.00 cm apart at t = 0 . Sketch the shape of the string at t = 0.250 s, t = 0.500 s , t = 0.750 s, t = 1.000 s and t = 1.250 s .

A string of linear mass density 0.5 g cm^-1 and a total length 30 cm is tied to a fixed wall at one end and to a frictionless ring at the other end. The ring can move on a vertical rod. A wave pulse is produced on the string which moves towards the ring at a speed of 20 cm s^-1 . The pulse is symmetric about its maximum which is located at a distance of 20 cm from the end joined to the ring. (a) Assuming that the wave is reflected from the ends without loss of energy, find the time taken by the string to regain its shape. (b) The shape of the string changes periodically with time. Find this time period. (c) What is the tension in the string ?
