Question $2(4$ points$)$

Two children seat themselves on a seesaw. The one on the left has a weight of $400$ N while the one on the right weighs $300$ N $.$ The fulcrum is at the midpoint of the seesaw. If the child on the left is not at the end but is $1\mathrm{.}50$ m from the fulcrum and the seesaw is balanced, what is the torque provided by the weight of the child on the right?

$600N*m$

$450N*m$

$-600N*m$

$-450N*m$

$0N*m$
