A long straight wire is carrying a current of 25 A. An electron is fired parallel to the wire with a speed = 7.0 × 105 m/s in the same direction as the current at a distance d = 2 cm from the wire. V= d electron 25 A a) What is the direction of the force acting on the electron? Select an option ✓ b) What is the magnitude of this force? Give your answer in N without units. Use exponential notations (e.g., 5 x 10-5 can be entered as 5e-5.) N c) Is it possible to compensate the force on the electron by adding a second wire that is carrying a current of 100 A? Assume that the current is flowing to the right, as in the wire with the 25 A current. If so, where this wire can be placed?
