Question

26) Neglect gravity for this problem. a) Determine the electric force on the proton. b) Determine the acceleration of the proton. (direction?) c) Determine the (x,y) components of vi. These will be in terms of 0. Remember: km/s + m/s, 1 km/s1000 m/s
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 R1.27 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
