Two people carry a heavy electric motor by placing it on a light board 2.30m long. One person lifts at one end with a force of 420N , and the other lifts the opposite end with a force of 650N .

Suppose the board is not light but weighs 180N , with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case?
