Question

value of 30 RPS in radius seconds -1 is a)30πb)60πc)90πd)120π​

Answer 1

☆ Correct question:

✏ Value of 30 RPS in radian/sec is....

☆ Answer:

✏ (B) 60π ✔✔

Solution :

➡ Given:

✏ Frequency of circulating body = 30 revolution per second

➡ To Find:

✏ Angular velocity in radian/sec unit

➡ Formula:

✏ Relation between frequency and angular velocity is given by

• ω = 2πf

➡ Calculation:

✏ ω = 2π × 30

✏ ω = 60π rad/s

Answer 2

Value of 30 RPS in radius seconds -1 is 60πc....

Option b) 60πc is your answer...✔️
