Elementary Charge The charge (q) of one electron is q = -1.60 x 10-19 coulomb The charge (q) of one proton is q = +1.60 x 10-19 C - +

Coulomb’s Law F is attractive if the charges are opposite q is the charge d is the distance from center to center ke is called the Coulomb constant ke = 8.99 x 109 N.m2/C2 F is attractive if the charges are opposite F is repulsive if the charges are like + -

Mathematical Relationships q1 q2 d (q1q2) d2 F 1 (1*1)/12 = 1/1 2 (2*1)/12 = 2/1 4 10 ½

Mathematical Relationships q1 q2 d (q1q2) d2 F 1 (1*1)/12 = 1/1 2 (2*1)/12 = 2/1 4 (4*1)/12 = 4/1 (1*1)/22 = 1/22 ¼ 10 (1*1)/102 = 1/102 1/100 1/2 1/(1/2)2 = 1/(¼)

Why does k have such strange units? ke = 8.99 x 109 N.m2/C2

Who figured out the value of k?

Coulomb’s Law Charles Coulomb measured the magnitudes of electric forces between two small charged spheres He found the force depended on the charges and the distance between them

Force Calculations If I put two protons, 1x10-3 meter apart what would happen? What are the forces acting on them? + +

Compare! What is the electric force between 2 protons 1x10-3 meter apart? Charge: 1.6 x 10-19 C ke = 9.0 x 109 N.m2/C2 What is the gravitational force between 2 protons 1x10-3 meter apart? Mass: 1.7 x 10-27 kg G = 6.7 x 10-11 N.m2/s2

Force Calculations What is the electric force between the same two particles? Felectric = 2.3x10-22 N What is the force gravity between two protons one meter apart? Fgravity = 1.9x10-58 N Ratio = 1.4x1039 The electric force is over 1039 times stronger than the force of gravity!
