-17- APTOMA 10 (a) Two parallel wires carry currents in opposite direction as shown in Figure Q10. Mas Ring I₂ 5.0 A 8.0 A 25 cm 30 cm 35 60 cm Figure Q10 Find the value of magnetic field strength and direction at positions C and D, respectively. (3 marks) (ii) What is the direction of the magnetic force experienced by the 8.0-A wire? (1 mark) (b) An electron is released at position D with an initial velocity of 300 m/s toward +y direction. What is the force acting on the electron? (c) (2 marks) A small metal ring is released vertically above position C. What is the direction of the induced current when it just entries the magnetic field region? (1 mark)
