प्रश्न
If Earth completes one revolution in 24 hours, what is the angular displacement made by Earth in one hour? Express your answer in both radian and degree.
उत्तर
Given,
time period of earth = 24 hours
Solution:
Earth covers 360° in 24 hours
∴ Angular displacement m 1 hour = `"360°"/24` = 15° (or) `π/12`
Angular displacement in radian = `"15°"/"57.295°"` = 0.262 rad
