5: Electric Charge
1. What happened to the test charge when brought near another positive charge and how did you use this fact to score a goal only using positive charges? Explain for both the practice charge and more difficult levels.
● The charge was propelled away from the positive charge. On harder levels , I put the positive charges on the outside path d the test charge to take. 2. What happened to the test charge when brought near a negative charge and how did you use this fact to score a goal only using negative charges? Explain for both the practice charge and more difficult levels.
● The test charge at first was attracted but then repelled. 3. After observing the electric field in your trials above, where was the electric field the strongest? What was the direction of the electric field?
● Positive charge Upwards 4. Did you notice a green arrow appear as the test charge started to accelerate, this arrow represented the electric force! If not, take another “shot” at the game above and come back to this question. When was the electric force the greatest?
● Electric force was the greatest when the positive/negative was close to the test charge
1. Discuss the symmetry between the laws of Charles Coulomb and Sir Isaac Newton regarding forces
● Coulomb's law has the force on one charged body due to another equal and opposite to the force on that other charged body due to the first.
2. Matt forgot to put the fabric softener in the wash. As his socks tumbled in the dryer, they became charged. If a small piece of lint with a charge of +1.25 E 19 C is attracted to the socks by a force of 3.0 E 9 N, what is the magnitude of the electric field at this location?
● 2.4*10^10 N/C 3. Suppose an electric field with a magnitude of 2.8 E 4 N/C at a certain location, points due south. If a charge of 4.0 E 6 C is brought to the location, what is the electrostatic force that acts on this charge?
● .11 N towards North
