ASK YOUR TEACHER | PRACTICE AN \\ Example 19.2 A Proton Moving in a Magnetic Field Goal Calculate the magnetic force and acceleration when a particle moves at an angle other than ninety degrees to the field. Problem A proton moves at 7.51 x 10% m/s along the x-axis. It enters a region in which there is a magnetic field of magnitude 3.00 T, directed at an angle of 60.0 with the x-axis and lying in the xy-plane (Fig 19.8). (a) Find the initial magnitude and direction of the magnetic force on the proton, (b) Calculate the proton's initial acceleration. Strategy Finding the magnitude and direction of the magnetic force requires substituting values into the equation for magnetic force, Equation 19.1, and using the right-hand rule. Applying Newton's second law solves v part (b). Figure 19.8 The magnetic force Fona proton is in the positive z- direction when and B lie in the xy-plane. (a) Find the magnitude and direction of the magnetic force on the proton. Substitute v = 7.51 x 10% m/s, the magnetic field F=qvBsin @ strength B = 3.00 T, the angle, and the charge of a F = (1.60 x 10719 C)(7.51 x 10% m/s)(3.00 T)(sin proton into Equation 19.1. : Apply the right-hand rule number 1 to find the initial Point the fingers of the right hand in the x-direction direction of the magnetic force.
