An electron moves to the left

1.An electron moves to the left with a velocity of 3.2 x 105 m/s and has a magnetic force of 5.6 x 10-17 N exerted on it. What is the magnitude of the magnetic field? Assume the charge has a value of 1.60 x 10-19 C.

 

2.The maximum current output of an 18 Ω circuit is 12 A. What is the rms voltage of the circuit? 

 

3.. A step-down transformer used in an automobile has a potential difference across the primary of 1800 V and a potential difference across the secondary of 12 V. What is the ratio of the number of turns of wire on the primary to the number of turns on the secondary?
