(a) Earth can be

Answer :

(a) Given-

Radius of Earth = R = 6400km

Time period of circular motion of object around the earth = T = 1day = 24 hours

At the equator,

For an object performing circular motion acceleration can be found as,


At latitude θ,

(b) Given-

Orbital radius of Earth around Sun = 1.5×1011 m

Time period of 1 revolution = 1 year =365 days

We know acceleration during circular motion is given by,

= 5.97×10-3m/s2
