1. Electrostatic Force

2. Review of electrostatics
Three methods of Charge transfer:
Friction
Conduction
Induction

3. Sticky tape Activity results
Charges of each tapes differed depending on each scenario
Bottom Tape and Bottom Tape – Repelled (same Charges)
Top and Top Tape – Repelled (same Charges)
Top and Bottom Tape – Attracts (Negative charge and Positive Charge)
Metal Rod and Tape – Attracted as the Metal Rod was with the Cloth (Negatively Charged)
Paper and Paper- Did not Charge as they both held same charges (Cancelled out)

4. Metric System

5. Gravitation & Coulomb

6. Coulomb’s Law General Equation

7. Example Problem
The force between two identical charges separated by 1 cm is equal to 90 N. What is the magnitude of the two charges?

8. Try it yourself *Electron-1.60 × 10−19 *Proton-1.60 × 10−19 C
Assuming that the radius between the Electron and Proton is 0.07nm, find the Electrostatic Force of the atoms acting on each other
