Question

By what factor does the radius of the electron beam path (r) change if the current through the Helmholtz coil (I) is doubled? Hint: Use e/m = 2V (5/4)3 a2/(N 4o Ir)2. the radius of the electron beam path increases by a factor of 2 the radius of the electron beam path increases by a factor of 4 the radius of the electron beam path decreases by a factor of the radius of the electron beam path decreases by a factor of 1 О 2 points Of the following options, which conditions for V or I produce the largest radius of the electron beam path r? Hint: Use em 2V(5/4)a²/(N uo Ir)?. Maximum land Maximum V Maximum land Minimum V Minimum land Maximum V Minimum land Minimum V
