The angular velocity for the daily rotation of the earth is
Correct answer: C. π/12 radian hr-1
- A. π/3 radian hr-1
- B. π/6 radian hr-1
- C. π/12 radian hr-1
- D. 12 radian hr-1
Explanation
The angular velocity (ω) is the scalar measure of rotation rate. In one complete rotation, angular distance travelled is 2π and time is time period (T). Angular velocity is given by the following formula: ω=2π/T The time period for one complete rotation of the Earth is 24 hours so ω=2π/24 =π/12
