Question

In the absence of a wave travelling on a tight rope fixed at both the ends, the potential energy per unit length on the rope is zero.

• A. True
• B. False

Answer 1

The correct option is B False

Potential energy of a string depends only on how much the string is stretchable and not on the wave passing through it. A wave passing through it can provide some energy, thereby stretching it
In the problem given, the string is already stretched by keeping it between two supports. Thus, potential energy is not zero
