An electron is released from rest in a uniform electric field . The electron accelerates vertically upward , travelling 4.50 m in the first 3 µs after it is released. ( a ) What are the magnitude and direction of the electric field ? b ) Are we justified in ignoring the effects of gravity ? Justify your answer quantitatively.
