question 29

Multiple Choice

Suppose a uniform electric field of 4 N/C is in the positive x direction. When a charge is placed at and fixed to the origin, the resulting electric field on the x axis at x = 2 m becomes zero. What is the magnitude of the electric field at x = 4 m on the x axis at this time?

• A) 0
• B) 1 N/C
• C) 2 N/C
• D) 4 N/C
• E) More information is needed to find the resulting field magnitude at this position.
