Explanation / Answer

The magnitude of the magnetic force is given by
        F = Bqv
The magnetic field is
        B = F/(qv)

=2.3 * 10 ^-4 N/14 * 10 ^-6 C (28 m/s)

=0.00586 * 10 ^-2 T

The fore on the particle is
       F = Bqv sin

=0.00586 * 10 ^-2 T(14 * 10 ^-6 C)( 6.3 m/s)sin 24

=2.1 * 10 ^-9 N
