1. A boy rubs his dog with a balloon. The dog gets 20,000 extra electrons.a. What is the charge on the dog?b. Then the boy rubs a piece of silk on his cat. The cat LOSES 30,000 electrons to the silk. What is thecharge on the CAT?c. Finally, the boy places his cat (20 kg) on frictionless ice and he places his dog (35 kg) standing 2maway on the edge of the ice.i. Calculate the electrostatic force on the CAT from the DOG. Do they ATTRACT or REPEL?ii. What is the initial acceleration of the cat?iii. What is the electrostatic force on the DOG from the CAT? Why is this answer the same as ordifferent from “i”?iv. What is the initial acceleration of the dog? Why is this answer the same as or different from “ii”?
