A particle with positive charge q field exist. = 3.68 x 10 -18 C moves with a velocity v = (51 + 5 - K) m/s through a region where both a uniform magnetic field and a uniform electric (a) Calculate the total force on the moving particle, taking B = F = X Fv = = N N N (5 + 2 + k) T and = (3 2) V/m. (Give your answers in N for each component.) (b) What angle does the force vector make with the positive x-axis? (Give your answer in degrees counterclockwise from the +x-axis.) counterclockwise from the +x-axis (c) What If? For what vector electric field would the total force on the particle be zero? (Give your answers in V/m for each component.) Ex Ey E = V/m V/m = V/m =
