Auniform magnetic field of magnitude 0.80 t in the negative z direction is present in some region of space. a uniform electric field is also present and is set at 76,000 v/m in the +y direction. an electron is projected with an initial velocity v0 = 9.5 × 104 m/s in the +x direction. find the y component of the initial force on the electron.
