Calculate the centripetal acceleation of...

Calculate the centripetal acceleation of a point on the equator of earth due to the rotatin of earth about its wn axis . Radius of earth ` = 6400 km`.

Text Solution

Verified by Experts

Centripetal acceleration, `a-c = R 4 pi^2 //T^2`
Here, `R= 6400 km and T= 24 hours. So
` a_c = (6400 xx (22/7)^2)/((24))^2 = 439 km h^(-2)`.
