Name:_____________________________Coulomb’s Law Quiz1. Coulomb is the unit of which quantity?a) Field strengthb) Chargec) Permittivityd)Force
2. Coulomb’s law is employed in
3. Can two objects push or pull on each other without touching? How?: Magnetism
4. Why do clothes sometimes stick together when they come out of the dryer?: Because of the positive andnegative charges5. How can two balloons repel each other without touching?: Yes because if they have different chargesthey will repel
Find the Force in the following math problems using this equation:****Notice we are not including the k constant. I want you to see the inverse relationship between thechanges in charge and distance without being overwhelmed with exponents.6.A.q1=10Cq2=20Cr=5m =8***Refer back to these numbers when answering the comparison questions.

Unformatted text preview: q2=20C r= 5m=4C. q1=10C q2=10C r=5m=4 D. What happened to the Force when a charge was cut in half?: The force also was cut in half7. A. q1=10C q2= 20C r=10m= 20 B. What happened to the Force when the distance was doubled?: It soubled 8. A. q1=10C q2=20C r=2.5m= 32 B. What happened to the force when the distance was cut in half?: The force was cut in half9. A. q1=20C q2=40C r=10m=80 B. What happens when the both charges are doubled and the distance is doubled?: Everything goes up 10. Explain Coulomb’s Law in your own words.Label the following images with the electrostatic forces acting on each other. Use arrows to show attraction or repulsion. The blue (-) circles have a negative charge of 30C. The pink (+) circles have a positive charge of 50C. The distance between each object is 40m. Find the Force acting on each object and label it. + + +---...
