A uniform electric field ofmagnitude E=270V/m is directed in the positive x direction. Aproton moves from the origin to the point (x, y)=(20.0cm,50.0cm).
a) Through what potential difference does the charge move?
b) What is the change in the potential energy of the chargefield system?
c) An electron is released at rest at the origin and it moves inthe +x direction. What would be its speed, Vf, after theelectron is released from rest and travels distrance d in theuniform E field? Please derive the express of vf as afunction of the given quantities: E, d, e (the elementary charge)and m (the mass of the electron).
