An electron moves through a uniform magnetic field. The magnetic field is given by B→ = (0.00i^ − 90.5j^ + 50.9k^) mT. At a moment in time when the velocity is v→ = (0.00i^ + vyj^ + 98400.00k^) m/s, the magnetic force acting on the electron is F→ = (2.59i^ + 0.00j^ + 0.00k^)×10−16 N. What is the value of vy? m/s
