Q3: A charged particle is projected with an initial speed Vo = 5.0 x 106 m/sec into the uniform field between the parallel plates shown. The direction of the field is vertically downward, and the field is zero except in the space between the two plates. The particle enters the field at a point midway between the plates. If the particle deflected downward and just misses the upper plate as it emerges from the field, If the charge of the particle is 1.6x10-19 C, and its mass is 9.1x10-31 kg, 1- What is the sign of the charge of the particle? 2- Calculate the magnitude of the electric field.
