GO Figure 12-62 is an overhead view of a rigid rod that turns about a vertical axle until the identical rubber stoppers A and B are forced against rigid walls at distances r A = 7.0 cm and r B = 4.0 cm from the axle. Initially the stoppers touch the walls without being compressed, Then force F → of magnitude 220 N is applied perpendicular to the rod at a distance R = 5.0 cm from the axle. Find the magnitude of the force compressing (a) stopper A and (b) stopper B. Figure 12-62 Problem 51.

For each of the actions depicted, determine the direction (right, left, or zero) of the current induced to flow through the resistor in the circuit containing the secondary coil. The coils are wrapped around a plastic core. Immediately after the switch is closed, as shown in the figure, (Figure 1) in which direction does the current flow through the resistor? If the switch is then opened, as shown in the figure, in which direction does the current flow through the resistor? I have the answers to the question, but would like to understand the logic behind the answers. Please show steps.
