Q.23. An aircraft executes a horizontal loop of radius 1 km with a speed of 900 km. Ratio of centripetal acceleration to acceleration due to gravity is
(a) 12.3
(b) 3.3
(c) 6.4
(d) None of these
Dear Student
​Radius of the loop, r = 1 km = 1000 m
Speed of the aircraft, v = 900 km/h 
Centripetal acceleration, 
Acceleration due to gravity, g = 9.8 m/s 2
ac /g= 6.4
