The following problem is presented four times to give you extra practice: Each figure shows a charge moving at velocity vin the presence of a magnetic field B. The charge can be positive or negative and is shown moving through the origin of a rectangular coordinate system. The plane formed by the v and B vectors is represented by a dashed square, and this plane is one of the three rectangular coordinate planes. You will be asked to determine the magnetic force vector FB acting on the moving charge as it passes through the origin. What is the magnetic force vector FB acting on the moving charge in terms of a scalar and unit vector, as seen in the figure to the right? Bxl Feyli FBzk Fezk Submit Answe Tries 0/2 what is the magnetic force vector FB acting on the moving charge in terms of a scalar and unit vector, as seen in the figure to the right? FBxi FBzk Submit Answer es o/2 what is the magnetic forceExplanation / Answer
We will apply right hand thumb rule in all the above cases which states that if the thumb points in the direction of the velocity and the fingers point in the direction of magnetic field then the direction of the palm gives the direction of magnetic field.
1st case The direction of the force will be Fbxi
2nd case The direction of force will be -Fbyj
3rd caseThe direction of force will be -Fbyj
4rth case The direction of force will be -Fbzk
