A particle of charge +3.2 x 10^-19 C is released in a uniform electric field with a voltage difference of 1 MV (Mega is x 10^6). What is the velocity of the particle after traveling 20m if it started at rest and has a mass of 6.7 x 10^-27 kg? (assume 100% energy transfer)

They dud not provide the region of the voltage the only info given was that it is a uniform electric field with a voltage difference of 1MV
