Question

Find the acceleration acting towards the earth , at that instant when the object is twice the distance from its radius if measured from center of the earth?(Radius of Earth-6400Km)​

Answer 1

Explanation:

Time period of earth's rotation is ,T=24h=86400 s

Angular velocity, ω=2π/T

Radius of earth, r=6400km=640000m

Now, centripetal acceleration ω2r=

T

(2π)

2r=0.034m/s
