The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.
Two forces P & 2P act on the particle if the first is doubled & the second enhanced by 20N.The direction of the resultant remains unchanged. What is the value of P.
