A proton moves at8.30106 m/s along thex-axis. It enters a region in which there is a magnetic field of magnitude2.36T, directed at an angle of 60.0°with thex-axis and lying in thexy-plane (see figure).(a)Find the initial magnitude and direction of the magnetic force on the proton.
N-- direction -- downwards, in the negative z-direction. backwards, in the negative y-direction. to the left, in the negative x-direction. forwards, in the positive y-direction. to the right, in the positive x-direction. upwards, in the positive z-direction.
(b)Calculate the proton's initial acceleration.
