Answer: I think it’s 20cm.
Answer:
b)
Explanation:
Let the amplitude of SHM is given as A
so the total energy of SHM is given as
now we know that
a)
kinetic energy is given as
here
so now we have
now its fraction with respect to total energy is given as
b)
Potential energy is given as
so we have
so fraction of energy is given as
