Chapter 3. Electric Potential • Constant electric field F qE - conservative? • The Electric Potential: V - Single Charge - Dipole potential energy function? E Const V ( x) Ex For a point charge at the origin: 1 q V (r ) 40 r Ch3 Quiz 1 There is an electric field given by E E0ix where E0 is a constant. What is the difference in the value of the electric potential due to this electric field between the origin and the point x=a, y=b? Ch3 Quiz 2 There is an electric field given by 2 2 E x ix y i y where and are constants. What is the difference in the value of the electric potential due to this electric field between the origin and the point x=a, y=b? Ch3 Quiz 3 There is an electric field created by some source at the origin given by c E 4 ir r where c is a constant and r is the distance from the origin; ir points out from the origin. What is the difference in the value of the electric potential due to this electric field between the point x=a, y=b and the point at infinity? What is the potential function corresponding to this electric field if instead of being at the origin the source of the electric field is at point x=a, y=b? Have a great day!
