A particle with a charge of −2.10×10⁻⁸ C is moving with an instantaneous velocity of magnitude 39.0 km/s in the x-y plane at an angle of 52.0 ∘counterclockwise from the +x axis.
a) What is the direction of the force exerted on this particle by a magnetic field with magnitude 2.00 T in the -x direction? ( -y, -x, +x, +y, -z, or +z)
