    1. The problem statement, all variables and given/known data
    two protons are 1.0m apart. find the force acting on them.
    q1= 1.602E-19C
    q2= 1.602E-19c

    2. Relevant equations

    i just dont get how to work it out
    3. The attempt at a solution
    ive got this far up to now [(9E+9)(1.602E-19)(1.602E-19)]/(1.0)². dont know where to go from here
