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)

Metric System

Gravitation & Coulomb

Coulomb’s Law General Equation

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?

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
