Unformatted text preview: b) Find the magnitude and direction of the electric field E at the point where the two spheres touch. Again, express your answer in terms of R, Q, and constants (e.g. , , etc.). c) Find an expression for the electric field E as a function of x , for any point on the x axis between x = 0 and x = R . Express your answer in terms of x , R, Q, and constants (e.g. , , etc.). d) The electric field at a point on the x axis between x = 0 and x = R , can point in the positive x direction or the negative x direction, depending on the value of x . At what value of x , between x = 0 and x = R , does the electric field along the x axis have its maximum value directed in the positive x direction? Express your answer as a multiple of R ....
