What is the resultant force acting on 500g object accelerating at 5m/s2

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
