Assertion-Reason▾

Assertion (Ꭺ)

In S. H. M. , the motion is ‘to and fro’ and periodic.

Reason (Ꭱ)

Velocity of the particle (where x is the displacement and k is amplitude)

Both Ꭺ and Ꭱ are true and Ꭱ is the correct explanation of Ꭺ

b.

Ꭺ is false but Ꭱ is true

c.

Ꭺ is true but Ꭱ is false

d.

Question number: 46

» Oscillations and Waves » Periodic Motion - Period Frequency

Assertion-Reason▾

Assertion (Ꭺ)

The periodic time of a hard spring is less compared to that of a soft spring.

Reason (Ꭱ)

The periodic time depends upon the spring - constant, and spring constant is large for hard spring.
