    Answer:

    a) 10.6V

    b) E = 4.9V/m, +x direction

    c) E = 4.9V/m, +x direction

    Explanation:

    You have the following function:

    V=a+bx  (1)

    for the potential in a region between x=0 and x=6.00 m

    a = 10.6 V

    b = -4.90V/m

    V=10.6V-4.90\frac{V}{m}x

    a) for x=0 you obtain for V:

    V=10.6V-4.90\frac{V}{m}(0m)=10.6V

    b) The relation between the potential difference and the electric field can be written as:

    E=-\frac{dV}{dx}=-b=-(-4.9V/m)=4.9V/m  (2)

    the direction is +x

    c) The electric field is the same for any value of x between x=0 and x=6m.

    Hence,

    E = 4.9V/m, +x direction
