  3. Definitions: $100 SI Defines this as the current in each of two long, straight parallel conductors 1m apart in a vacuum, when the magnetic force between them is 2x10-7 N/m length. What is an Ampere?

  4. Definitions: $200 The units for this is Newton times metres squared divided by kilogram squared (N*m2/kg2). What is the Universal Gravitation Constant?

  5. Definitions: $300 This is the minimum speed needed to project a mass m from the surface of mass M to just escape the gravitational force of M. What is Escape Speed/Velocity?

  6. Definitions: $400 A charged particle in a uniform electric field is said to move with this type of acceleration. What is Uniform/Constant Acceleration?

  7. Definitions: $500 If an object experiences a particular kind of force over a continuous range of positions, then this exists in that region. What is a Force Field?

  8. Magnetic Field of Dreams: $100 This symbol is used to indicate that the magnetic field is going into the page. What is the circle with an x in it?

  9. Magnetic Field of Dreams: $200 A horizontal wire carries a current to the right, through a magnetic field. The force acting on the wire is out of the page. What is the direction of the magnetic field? What is vertically up?

  10. Magnetic Field of Dreams: $300 The magnitude of the magnetic field a distance r from a long, straight I is B. The same magnetic field will have magnitude 2B if the current is tripled at this distance. What is 1.5r ?

  11. Magnetic Field of Dreams: $400 A straight wire 15 cm long, with a current of 2 A, lying at right angles to a uniform magnetic field, experiences a magnetic force 0.40 N. What is the magnitude of the magnetic field? What is B = 1.3 T?

  12. Magnetic Field of Dreams: $500 A charged particle moves in a straight line through a region of space. Could there be a nonzero magnetic field in this region? If so, give examples. What is yes, parallel in the same/opposite direction or with a crossed electric field?

  13. Don’t Break the Law: $100 When a current is induced in a coil by a changing magnetic field, the electric current is in such a direction that its own magnetic field opposes the change that produced it. What is Lenz’s Law?

  14. Don’t Break the Law: $200 This law states that the force between two point charges is inversely proportional to the square of the distance between the charges and directly proportional to the product of the charges. What is Coulomb’s Law?

  15. Don’t Break the Law: $300 This law states the force between any two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres. What is Newton’s Law of Universal Gravitation?

  16. Don’t Break the Law: $400 This law states that if you are not punctual to your physics class you will have lunch time detention. What is the Law of Mr. Chang/Law of the Land?

  17. Don’t Break the Law: $500 This law states that the total charge (the difference between the amounts of positive and negative charge) within an isolated system is conserved. What is the Law of Conservation of Charge?

  18. May the Force be with You: $100 What is the magnitude and direction of the magnetic force on an electron travelling at 5.0 x 104 m/s in the same direction as a uniform magnetic field with a strength of 5.0 T? What is zero?

  22. May the Force be with You: $500 How much current is flowing in a wire 4.80 m long if the max force on it is 0.750 N when placed in a uniform 0.0800 T field? What is I = 1.95 A ?

  23. Don’t Formulae to Me: $100 This formula allows you to determine the Magnetic Field Strength at any distance away from a current carrying wire. What is B = moI/ 2pr?

  24. Don’t Formulae to Me: $200 This formula determines the magnitude of the force on a current carrying conductor in a magnetic field. What is FM = IlBsinq ?

  25. Don’t Formulae to Me: $300 This formula allows you to determine the magnitude of the electric field at any point in the space between two large parallel plates. What is e = V/r ?

  26. Don’t Formulae to Me: $400 This formula allows you to determine the force on a moving charge in a magnetic field. What is FM = qvBsinq ?

  27. Don’t Formulae to Me: $500 You would derive this expression for the velocity of a satellite using Newton’s Law of Universal Gravitation and Newton’s Second Law. What is v = sqrt(GmE /r) ?
