Answer:
Centripetal force experienced by the moon when it revolving around earth = m×ω2×R ....................(1)
where m is mass of moon, ω is angular speed, R is mean distance from earth.
Centripetal acceleration = ω2×R = ω2×60×RE = ( 4π2/T2 )×60×RE .........................(2)
where RE is earth's radius. T is time period for one revolution around earth which is 27.3 days
Centripetal acceleration = 
m/s2 .....................(3)
m/s2 .....................(3)we compare the centripetal acceleration calculated in eqn.(3), i.e 9.8 / (2.712×10-3 ) = 3614
