A uniform 40-N board supports two children weighing 500 N and 350 N. If the support is at the center of the board and the 500-N child is 1.5 m from its center, How far is the 350-N child from the center determine the upward force exerted on the board?​

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
