Question

• Review the process of charging on object. What is the difference between charging an object through induction and one through conduction? • Understand Coulomb's law and the superposition principle. Use Coulomb's Law to solve problems dealing with the electric force between point-like objects. Example problem: Given two charges of q, and q, can you find a place to put a third charge of q, such that the resulting electric force from q, and q, is zero? Chapter 23: The Electric field Review the definition of the electric field and how to define its direction. How do you define a test charge and how do positive and negative charges move in an electric field? • Review the definition of a dipole. What is the dipole moment? What is the difference between a permanent and induced dipole moment? • Review how to calculate the electric field for rigid shapes. Review concepts of charge density. • Review the electric field generate by a charged rod, ring of charge, charged disk, and charged sphere. Example problem: A thin wire carries uniform charge. Find the electric field at a point P on a line that bisects the wire Example problem: A particle is fired into a uniform electric field, produced by two conducting plates, in the direction of the electric field. Find the velocity of the particle after some distance.
please provide answers to the "examples". any brief explanation of the topics would help me immensely!
