Need help solving for d) and e)
26. Protons are projected with an initial speed v GP 9.55 km/s from a field-free region through a plane and into a region where a uniform electric field E 720j N/C is present above the plane as shown in Figure P22.26. The initial velocity vector of the protons makes an angle θ with the plane. The protons are to hit a target that lies at a horizontal distance of R 1.27 mm from the point where the protons cross the plane and enter the electric field. We wish to find the angle θ at which the protons must pass through the plane to strike the target. (a) What analysis model describes
Е -720j N/C × Target Proton 1 beam E 0 below the plane Figure P22.26
d) Using Viy, find the time t, it takes to reach max height (in terms of θ), what is the clue for max height problems? e) The time to hit the target (x R (in m)) is 2t. Use Vix (part c), and the time (part d), write the equation for x- vixt: R VxI(2t). This will be in terms of e, and if you do this correctly, your answer should be (something)sinecose. f) There is a trig identity: sinecosθ .5sin20. This is sin (20), not sin20. Substitute this into your expression from part e), then solve for e g) With e, determine the numbers for Vix, Xiy, and t. (b
