Question

The speed of a body, taking one round on circular path of radius r in time t is​

Answer 1

Answer:

Velocity = 0

Speed = 2πr/t

Explanation:

If a body takes t seconds to go once round the circular path of radius r the velocity v is given by

In Completing one round

Distance Covered = 2πR

But Displacemnt = 0

Time taken = t sec

Velocity = 0 as Displacement = 0

Speed = 2πr/t

Answer 2

Answer:

Speed = 2πr/t

Explanation:

If a body takes t seconds to go once round the circular path of radius r the velocity v is given by

On Completing one round ,

Distance Covered = 2πR

But Displacement = 0

Time taken = t sec

Velocity = 0  as Displacement = 0

Speed = 2πr/t
