To apply Problem-solving Strategy 20.1 Magnetic forces.
At a given instant, a particle with mass 5.00 x 10⁻³ kg and charge 3.50 x 10⁻⁸ C has velocity of magnitude of 2.00 x 10⁵ m/s in the +y direction. It is moving in a uniform magnetic field of magnitude 0.8 T directed 40 degrees clockwise from the -x direction. What are the magnitude and direction of the magnetic force on the particle?
what is the magnitude f of the magnetic force on the charge?
