question 16

Multiple Choice

The potential as a function of position x is shown in the graph in the figure. Which statement about the electric field is true?

• A) The electric field is zero at x = 0, its magnitude is at a maximum at x = 5 cm, and the field is directed to the right there.
• B) The electric field is zero at x = 5 cm, its magnitude is at a maximum at x = 0, and the field is directed to the right there.
• C) The electric field is zero at x = 0, its magnitude is at a maximum at x = 15 cm, and the field is directed to the left there.
• D) The electric field is zero at x = 10 cm, its magnitude is at a maximum at x = 5 cm, and the field is directed to the left there.
