)Refer to figure 1: Two 2.00x10-5 C charges are 1.00x10-3 m away from each other. Calculate the force acting on them. Determine whether they will attract or repel one another. Then calculate the final velocity and displacement after XXXXXXXXXXseconds of the “dotted” charge if the other charge is anchored.
Figure 1: Both objects are 3.0x10-4 kg each.
2. What is Coulombs Law? How is it similar to Newton’s Law of gravity?
3. What is the charge and mass of an electron?
