Which scenario represents the strongest force? (assume particles in all scenarios are the same distance apart.)

protons and neutrons are held together inside the nucleus.

two particles are attracted to one another by static electricity.

an unstable atom breaks down releasing two radioactive particles.

two rocks of equal mass fall to the ground at the same speed.

Sorry i don’t know what to do

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
