Question

Angular speed is the rate of change of angular displacement, which is the angle swept by the radius vector per unit time.

विकल्प

• v = \[\frac {r}{T}\]

• v = \[\frac {2πr}{T}\]

• v = \[\frac {T}{2πr}\]

• v = rω

Answer 1

v = \[\frac {2πr}{T}\]

Explanation:

Linear speed is distance (circumference 2πr) divided by the time taken (Period T).
