A uniform electric field has magnitude E = 270 N/C and is directed to the right. A particle with charge +4.3 nC moves along the straight line from a to b that is 0.25m in length
(a) What is the electric force that acts on the particle? magnitude ? µN direction ? to the left to the right
(b) What is the work done on the particle by the electric field? uJ
(c) What is the potential difference Va ? Vb between points a and b? ? V
