Electrons on the outermost shell/energy level
Answer:
F = 1024 N
Explanation:
Given that,
Mass of the cart, m = 80 kg
Radius of the loop, r = 5 m
Speed of the cart, v = 8 m/s
To find,
the force exerted on the track on the cart.
Solution,
The force exerted on the track on the cart is called centripetal force. When an object moves in a circular path it possess centripetal force. It is given by :
F = 1024 N
So, the force exerted on the track on the cart is 1024 N.
