An electron moving with a velocity v = 5.0 × 10^7 m/s i enters a region of space where perpendicular electric and a magnetic fields are present. the electric field is e = 104 v/m j. what magnetic field will allow the electron to go through the region without being deflected?

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
