and

x = 5.0\,\text{cm}

with potentials

+30\,\text{V}

and

+20\,\text{V}

, respectively. What is the direction of the electric field at a point located at

x = 3.0\,\text{cm}

? a) Along the

+y

direction b) Along the

-x

direction c) Along the

+x

direction d) The electric field is zero at

x=3\,\text{cm}
