According to the biot-savart force law and the right hand rule, if a magnetic field is directed rightward (+ x axis) and a positive test charge moves through the field downwards (- y axis), which direction will the magnetic force be applied onto the charge? 1. upwards (+ y axis) 2. leftward (- x axis) 3. out of the screen (+z axis) 4. into the screen (- z axis)

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
