$\bullet$ A proton traveling at 3.60 $\mathrm{km} / \mathrm{s}$ suddenly enters a uniform magneticfield of 0.750 $\mathrm{T}$ , traveling at an angle of $55.0^{\circ}$ with the field lines (Figure 20.57$)$ . (a) Find the magnitude and direction of the force this magnetic field exerts on the proton. (b) If you can vary the direction of the proton's velocity, find the magnitude of the maximum and minimum forces you could achieve, and show how the velocity should be oriented to achieve these forces. (c) What would the answers to part (a) be if the proton were replaced by an electron traveling in the same way as the proton?

for the given problem. We have a following situation. A particle Ah Proton is moving in. Ah J K EPT direction. This is the unit Director. Ah, we level it for the pro TEM. Moving with speed. We up in a manic field is acting in this direction and we could level this very the unit vector that is I kept the angle between B and B's and 55 degrees for about a off the problem. We can write the main street of force using an equation that is charged on a proton. So Cuma, I will write for the charge in the proper tone time we cross B we lost you for brought on times Ah ah times the Manti three old times a sign off 55 degrees This tangle between me and be then substituting the values We have 1.602 times 10 to the power minus 19. Coolum is for brought on times and we 3.60 times sending powers three meters per second times. Ah, it'd feel we have a 0.750 Tesla time sign 55 degrees. And this gives us a major force that is a full 0.32 times 10 to the power minus 16. Um, while the 16 this this is the factor, actually multiplies with sign or 55 which gives us the force, or for 3.54 down, stand to the power minus 16 Newton. Um, the force will be then into the cage. In this direction, we can write this force using a right and rule, or we can just take the cross productive cough J J unit worker with I, which will give us a minus k. So this will be into the page for a part B off the problem If the angle between Avi and to be is ah, 90 degree or 1 80 You know, you know the words. If they are paler and paler, the air force will be minimum, which is equal thio zero. If the angle between we and be his nineties or they are perpendicular to each other, then the force will re maximum, which is a call to full point 3 to 5 times 10 to the power minus 16. Um, minus 16 Newton. This is for the angle where when the angle is 90 degrees for part C. Um, For this case, the force will be out off the page for electron. And, uh, because the electron has got to send charges brought on. So the main chewed off the force will be Sam for 55 degrees, which is 3.54 times 10 to the power minus 16 Newton. And this is out off the bitch.
