Question

What is the angular displacement of second hand in 2

seconds​

Answer 1

Answer:

In 60 sec ,

Angle turned by second hand = 2 × Pie radians

In 1 s , angle turned = ( 2 × Pie ) / 60 radians

In 2 s , angle turned = 2 × ( 2 × Pie ) / 60 radians

Here angle turned by the second hand is the angular displacement and denoted by greek letter THETHA , say @

Thus @ = ( 2 × 2 × Pie ) / 60 radians

= Pie / 15 radians
