Plz me 3 miins 50 points and brainleist

juan uses a lever to lift a rock. he places the rock on the short arm of the lever and pushes down on the other arm of the lever. he applies 30 n of force over a distance of 1 m. the other end of the lever moves in the opposite direction and raises the rock a distance of 0.2 m. what is the weight (force) of the rock
what is the mechanical advantage of the lever in question 1?

I calculated the mechanical advantage. It is in the picture above

but I haven't gotten the weight but I know the general formula of weight 2 be m×g (mass ×gravity) I will get back 2 u once I solve it plz don't be offended and plz Mark me brainliest answer

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
