Homework Statement
An alpha particle (two protons and two neutrons) traveling east at 2.0 x 105 m/s enters a magnetic field of 0.20 T pointing straight up. What is the force acting on the alpha particle?
Homework Equations
F = qvBsinø
The Attempt at a Solution
With the fingers of the right hand pointing straight up, and the thumb pointing east, the palm points south.
F = qvBsinø = (2 x 1.6 x 10-19 C)(2.0 x 105 m/s)(0.20 T)sin90º = 1.28 x 10-14 N
Need a little help on the direction. This was the answer found when I checked it, but that can't be right. Isn't the correct answer [out]?
