Question

The earth, radius 6400 km, makes one revolution about its own axis in 24 hours. The centripetal acceleration of a point on its equator is nearly

Answer 1

Solution:-

the time period of earth’s rotation is,

T = 24 h = 86400 s

Angular velocity, ω = 2π/T

Radius of earth, r = 6400 km

=> 640000 m

Now, centripetal acceleration = ω^2r

=> (2π/T)2r = 0.034 m/s^2

= 3.4 cm/s^2
