Mid-term Name: ID: k 1 k 1 - (8 points each question) 1. Charge Q1 of is placed 1 meter away from charge Q2 of . The quantity k is 8.99×10 9 Nm 2 /C 2 , the constant in Coulomb’s Law. What is the force on Q2? 1. State Gauss’s Law and Ampere’s Law in your own language and write out the formulas. 1. State Faraday’s Law of induction and write out the formula, and state Lentz Law in your own language. 1. A high voltage generator is made of a metal sphere with a radius of 6 cm sits on an insulating post. A wire connects to the sphere’s inner surface through a small hole. The wire carriers a current of 1 μA and flows into the sphere when the switch is closed. One (1) minute after the switch is closed, what is the electric potential at the surface of the sphere assuming potential far away from the sphere is zero? 5. A straight wire of cross section A and length L has a resistance R and is connected to a battery of emf V , ignore the internal resistance. A certain amount of heat H is
