A string of length 40 cm and weighing 10 g is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 160 N/m and is stretched by 1.0 cm. If a wave pulse is produced on the string near the wall, the time it will take to reach the spring is 1/x. The value of x is ?
The tension in the string
F = kx = 160 × 0.01 = 1.6 N
The mass per unit length of the string
The speed of transverse wave
The time taken by wave pulse to reach the spring
