Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A dipole field pattern is shown in the figure. Consider various relationships between the electric potential at different points given in the figure. G R S X K +- Notice: Five potential relationships are given below. a) V R = V X > V S b) V R = V X = V S c) V R = V X < V S d) V G < V S < V K e) V G > V S > V K Which relations shown above are correct? 1. ( e ) only 2. ( a ) only 3. ( c ) and ( d ) only 4. ( b ) and ( e ) only 5. ( a ) and ( e ) only 6. ( d ) only 7. ( c ) and ( e ) only 8. ( a ) and ( d ) only 9. ( b ) and ( d ) only 10. ( c ) only 002 (part 1 of 4) 10.0 points Two charges are located in the ( x, y ) plane as shown in the figure below. The fields pro- duced by these charges are observed at the origin, p = (0 , 0). The Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . x y- Q- Q p b a a Use Coulomb’s law to find the x-component of the electric field at p . 1. E x = 2 k e Qa ( a 2 + b 2 ) 3 / 2 2. E x =- k e Qa ( a 2 + b 2 ) 3 / 2 3. E x = 2 k e Q a 2 + b 2 4. E x = 0 5. E x =- 2 k e Qa ( a 2 + b 2 ) 3 / 2 6. E x =- 4 k e Qa ( a 2 + b 2 ) 3 / 2 7. E x =- 2 k e Q a 2 + b 2 8. E x = k e Qa ( a 2 + b 2 ) 3 / 2 9. E x = 4 k e Qa ( a 2 + b 2 ) 3 / 2 003 (part 2 of 4) 10.0 points Let: V = 0 at infinity.= 0 at infinity....
