Question

consider a motion of particle with mechanical energy if you didn't notice the potential energy ke din notes kinetic energy and ID notes mechanical energy then which of the following is not possible
a.U<E
b.U>E
c.K>E
d.K<E​

Answer 1

Answer:

ANSWER

In SHM ω=

m

k

E=

2

1

mω

2

A

2

Substituting the value of ω

E=

2

1

m

m

k

A

2

E=

2

1

kA

2

Hence we can clearly see that energy E is independent of mass

So if maas m is replaced by a mass

2

m

Energy will remain same E
