Problem 12
Q

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