    1. The problem statement, all variables and given/known data[/b]

    The electric potential in a region of space is given by V = axy where a = 1.7 V/m2.

    (a) What is the electric field at the point x = 3.5 m, y = 2.0 m? Give your answer in unit
    vector notation.

    (b) If a particle of mass m = 1.67 × 10 −27 kg and charge q = +1.6 × 10 −19 C is released from
    this point, what is the magnitude of its initial acceleration?

    2. Relevant equations


    3. The attempt at a solution
    This seems to simple is this correct. Also do not understand unit vector notation.
    (b) unsure of the equation to use
