Question

The electric potential within a charge distribution is given by \(V = \frac{A}{a^2 + x^2 + y^2 + z^2}\) where V is in volts, A is in volts-meters$^2$, and a, x, y, and z are in meters. a) Find an expression for $E_x$, the x component of the electric field. b) Find an expression for $E_y$, the y component of the electric field. c) Find an expression for $E_z$, the z component of the electric field. If A = 1.50 V-m$^2$ and a = 0.08 m, then calculate the potential V at the point P with coordinates (0.02 m, 0.04 m, 0.04 m).

Step 1

The electric field is the negative gradient of the electric potential, so we can write: E = -∇V where ∇ is the gradient operator. In Cartesian coordinates, the gradient operator is given by: ∇ = (∂/∂x)i + (∂/∂y)j + (∂/∂z)k where i, j, and k are the unit Show more…
