Q4. A proton travels through unifom magnetic and electric fields. The magnetic field is B = -2.5 įmT. At one instant the velocity of the proton is v = 2000i m/s. At that instant and in unit-vector notation, what is the net force acting on the proton if the electric field is (a) 4 k v/m (b) - 4 k v/m, and (c) 4 į v/m?
