Problem 12
Q
Find the direction of the force on a negative charge for each diagram shown in Fig. 20–52, where $\vec{v}$ (green) is the velocity of the charge and $\vec{B}$ (blue) is the direction of the magnetic field. ($\otimes$ means the vector points inward. $\odot$ means it points outward, toward you.)
