The angular velocity and the amplitude of a simple pendulum is

\omega

and

a

respectively. At a displacement

x

from the mean position, if its kinetic energy is

T

and potential energy is

V

, then the ratio of

T

to

V

is

View answer and explanation

Correct option: C

\left(a^2-x^2\right) / x^2

Option C (

\left(a^2-x^2\right) / x^2

) is correct because it is derived from the formulas for kinetic and potential energy in simple harmonic motion.

Assertion: A particle executing simple harmonic motion comes to rest at the extreme positions.

Reason: The resultant force on the particle is zero at these positions. A particle is subjected simultaneously to two SHM’s one along the

x

-axis and the other along the

y

-axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute A particle is executing SHM with amplitude
