Using your equation for the relationship between strands of spaghetti and number of marbles to break the strands, determine how many marbles are needed to break a 50
strand spaghetti bridge?

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

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
