The Electric Potential at a Certain Point Is Given by V

Question 33

Multiple Choice

The electric potential at a certain point is given by V = -7.5x2 + 3x, where V is in volts and x is in meters.What is the electric field at that point?


A) The electric potential at a certain point is given by V = -7.5x<sup>2</sup> + 3x, where V is in volts and x is in meters.What is the electric field at that point? A) = (15x - 3) B) = (-15x + 3) C) = (-2.5x<sup>3</sup> + 1.5 x<sup>2</sup>) D) = (2.5x<sup>3</sup> - 1.5 x<sup>2</sup>) E) = 0 = (15x - 3)
