Answer:

Step-by-step explanation:

This is a torque problem where balance is achieved when the sum of the torques equal 0. The equation for torque is


\tau=F*r where F is the force in Newtons that is perpendicular to the lever arm, and r is the length of the lever arm in meters.

450(2) = 350r and


(450(2))/(350)=r so

r = 2.6 m
