Three wagons, each of mass m are being pulled by an engine exerting a froce F on the lead wagon. What is the fore exerted on the last wagon by the middle wagon?

A

F

B

`F/3`

C

`(2F)/3`

D

`F/2`

Text Solution

Verified by Experts

The correct Answer is:
B
The acceleration of the system
`=(Force)/( T otal mass)=F/(3m)`
`therefore T_2 = m times a = m times F/(3m)= F/3`

A horse is urged to pull a wagon the horse refuses to try, citing Newton's third laws as a defense: the pull of the horse on the wagon is equal to but opposite the pull of the wagon on the horse. "If I can never exert a greater force on the wagon than it exerts on me, how can I ever start the wagon moving ?" Asks the horse. How would you reply ?
