Two particles, A and B, are in uniform circular motion about a common center. The acceleration of particle A is 4.9 times that of particle B. The period of particle B is 2.4 times the period of particle A. The ratio of the radius of the motion of particle A to that of particle B is closest to.

Explanation:

given,

Acceleration of Particle A = 4.9 times particle B

Period of particle B = 2.4 times Period of A

Ratio of radius of the motion of particle A to B = ?

For Particle A

For Particle B

Form the question

and

Hence, the ration of the radius of the Particle A that of B = 0.85.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
