In the adjoining figure, two pulses in a stretched string are shown. If initially their centres are apart and they are moving towards each other, with speed of , then total energy of the pulses after will be
Options:
Answer:
B
Solution:
Given, speed of each pulse Therefore distance travelled by both pulses in toward each other. On their superposition, the resultant displacement at every point will be zero. Hence, total energy will be purely kinetic.
