Read a set of data from the image, that is, when the force f is equal to 0.6N, the corresponding force arm is 5cm, so when the lever is balanced, the product of the resistance and the resistance arm is 0.6N×5cm=3N? Cm and remain the same, then F=3N? cmL。

So the answer is F=3N? Currentmodelogic current-mode logic
