Question

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.

Answer 1

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
