PROBLEM SOLVING: SHOULD INCLUDE THE FOLLOWING: GIVEN, FORMULA, COMPLETE SOLUTION WITH UNIT ANALYSIS. 1. Magnetic force on a proton. A magnetic field exerts a force of 9 X 10-10 N toward the west on a proton moving vertically upward at a speed of 5 X 106 m/s. Determine the magnitude of the magnetic field. 2. A 2.50-m segment of wire supplying current to the motor of a submerged submarine carries 1000 A and feels a 4.00-N repulsive force from a parallel wire 5.00 cm away. What is the direction and magnitude of the current in the other wire? 3. A proton moves at 7.50 m/s perpendicular to a magnetic field.The field causes the proton to travel in a circular path of radius 0.800 m. What is the field strength?
