Question

If our first vector a is in the positive x-direction and our second vector b is in the Positive y-direction. what is the direction of c? If we now consider b times a instead of a times b, what is the direction of c (This makes b the first vector now and a the second vector). Does this match your results from the previous page? Magnetism: The real equation for magnetic force is F_B = qv times B, this means that you can use the same right hand rule as we were using for the cross product where our v vector is the first vector, our B vector is the second vector, and our F_B vector is the resultant vector. If a proton is moving in the positive x-direction through a magnetic field oriented in the positive y-direction, what is the direction of FB? If a proton is moving in the positive y-direction through a magnetic field oriented in the positive x-direction. what is the direction of F_B? If a proton is moving in the positive y-direction through a magnetic field oriented in the positive y-direction, what is the direction of F_B? Explain Why.

Here I have explained the problem by simply using the conventional unit vectors along X, Y and Z directions. We also can solve the problem using right hand screw rule by taking the reference axes as shown in the figure above
