What is the magnitude of the force on the charge?  a. 1.00 N b. 1.44 N c. 0.72 N  d. 1.25 N 2. What is the direction of the force on the charge? a. Into the earth  b. Out of the earth c. North 60 degrees above horizontal d. South 30 degrees below horizontal

uppose you are working on a science lab in which your professor asks you to turn a knob 750 on the detector you are using. Unfortunately, you have been working in radians for a while, so you are having trouble remembering how far to turn the knob. How would you translate the instructions in degrees to radians?

2. The current goes around a rectangular conducting frame as shown. The frame sits in the external magnetic field 5. a. Use = x to determine the direction (+x/-x/+y/-y/+z/-z/zero) of the torque on the rectangular loop. b. We can also determine the torque by analyzing the force that the external magnetic field exerts on the different segments of the square frame. Give the direction (+x/-x/+y/-y/+z/z/zero) of the magnetic force on each section of the frame: I. Force on the top leg of the current loop. II. III. IV. V. Force on the right leg of the current loop. Force on the bottom leg of the current loop. Force on the left leg of the current loop. +z 1 +y B +8 Use your analysis of the forces to determine the direction of the torque on the frame. Check that this is consistent with your answer to (a).
