What is the centripetal force for an object of mass 50 Kg with the following specifications moving in a uniform circular motion.
Distance between the object and the axis point is 20 cm. Object’s speed is 30 m/s.
- – 225000 N
- 225000 N
- 0.07 N
- – 0.07 N
Hint:
The correct answer is: 225000 N
mass = 50 kg
radius = 20 cm =0.20m
speed = 30 m/s
