Question
One projectile after deviating from its path starts moving round the Earth in a circular path of radius equal to nine times the radius of Earth R. Its period will be : -
Options
A.2π
B.27 × 2π
C.π
D.0.8 × 3π
Solution
Net force towards the centre ⇒ mω2(9R) = 
⇒ ω2 =
⇒ T = 
⇒ 27 × 2π
⇒ ω2 =
⇒ T = ⇒ 27 × 2πCreate a free account to view solution
