Solution

The correct option is C The total energy is in form of kinetic energy
When the string is such that the net displacement because of both the pulses is not zero. The total energy is distributed in kinetic and potential energy. When string has no displacement, there is no potential energy. Potential energy basically arises due to stretching of string which would be zero in such case and as we know all energy is conserved. The total energy is only kinetic!
