A particle with charge +7.88 μC is placed at the fixed position x = 3.00 m in an electric field of uniform strength 300 N/C, directed in the positive x direction. Find the position on the x axis where the electric field strength of the resulting configuration is zero. I dont understand this problem. I thought if the electric field is of uniform strength, then the strength would be 300N/C throughout the field. How can the field strength be zero?
