Imagine that you are able to go on a fishing trip that you have always wanted to. Your friend gets a bite that exerts a force of about 50N on the pole and it bends by a certain amount. Now you have a pole identical to your friends and you get a hit that bends the pole about twice as much. You can estimate that the force on your pole is about
A) Can't tell
B) 100 N
C) 200 N
D) 500 N

Question

Quizplus · Accepted Answer
