Auniform electric field has a magnitude 1.80 kv/m and points in the +x direction. (a) what is the electric potential difference between x = 0.00 m plane and the x = 3.60 m plane? v(3.60 m) = kv (b) a point particle that has a charge of +2.90 µc is released from rest at the origin. what is the change in the electric potential energy of the particle as it travels from the x = 0.00 m plane to the x = 3.60 m plane?
