The device pictured is called a velocity selector. Two charged plates are placed in a uniform B-field, so that the direction of the E-field between them is at a right angle to the direction of the B-field. Charged particles are then sent through the plates. Only those for which the electrical and magnetic forces exactly cancel out are allowed to pass to the far end. If we send hydrogen nuclei (that is, protons) into the selector with the strength of the E-field at 2000 N/C and the strength of the B-field at 0.8 T, what is their velocity if they make it through

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
