Electrostatic Force Opposites Attract Like Charges Repel Holds Atom together!

Electrostatic Force Opposites Attract Like Charges Repel Holds Atom together!

e -1 Q = Charge r = distance K = constant Positive Force = repulsive Negative Force = attractive p +1 e -1 p +1

Q1Q1 Q1Q1 Q2Q2 Q1Q1 Q1Q1 Q2Q2 Q = Charge r = distance K = constant The greater the charge the greater the force. The closer the charged particles are, the stronger the electrostatic force.

Q = Charge r = distance K = constant If you double the charge you double the force

p +1 r=1 p +1 r=2 p +1 r=3 p +1

e -1 p +1 r=1 e -1 p +1 r=2 e -1 p +1 r=3 If you double the distance you reduce the force by 4x times as much. If you triple the distance you reduce the force by 9x as much.

1.Opposite Charges ________________. Like charges ________________. If charge increases then force ____________. If distance increases then force _________. 1.Explain the inverse square law and its importance. 2.If the value of the charge on an object quadruples, what happens to the value of the electrostatic force? 3.If two charges separated by 1 nanometer are moved twice as far apart, what happens to the value of the electrostatic force between them? 4.If the distance between two charges is cut in half, what happens to the value of the force? 5.If you double both the total charge of an object and the distance between those two objects, what happens to the value of the electrostatic force? 6.Considering the actual charge of a proton is (35)×10 −19 C and an electron is (35)×10 −19 C what would be the electrostatic force between them at a distance of 1 nanometer (1.0 × meters). Assume K = ×10 9 N·m 2 /C 2.
