2. Using Right Hand Rule #1, determine the magnetic force direction for each of the three situations shown. 90 (a). Positive charge 90 (b) Positive charge 90 (c) Negative charge 3. The figure below shows a proton moving in a uniform magnetic field directed out of the page. B = 27.5 mT and v= 250.0 m/s. B a) Draw the force vector in the figure for the magnetic force on this proton. b) Will the proton go in a circle that is clockwise or counterclockwise? c) Calculate the radius of the circle.
