As the pulses interfere destructively there is a point in time when the string is perfectly straight. Which of the following statements is true at this moment?

Answer :

Answer:

The string posses kinetic energy only.

Explanation:

In the case of two pulses interfere destructively, the string is momentarily straight. The resultant amplitude which is produced by the wave pulse will be zero.

Therefore, the potential energy will be zero then the total energy contains only kinetic energy.

Therefore the energy is in the form of kinetic energy.
