A uniform electric field has a magnitude 2.30 kV/m and points inthe +x direction.

(a) What is the electric potentialdifferencebetween x = 0.00 m plane and the x =4.20 m plane? kV

(b) A point particle that has a charge of +2.90 µC is released fromrest at the origin.What is the change in the electric potentialenergy of the particleas it travels from the x = 0.00 mplane to the x= 4.20 m plane?
mJ

(c) What is the kinetic energy of the particle when it arrivesatthe x = 4.20 m plane?
