Question

Find the electric field strength vector if the potential of this field has the form φ = ar, where a is a constant

Answer 1

Determine the electric field strength vector if the potential of this field depends on x, y coordinates as 

(a) φ = a (x2 — y2); 

(b) φ = axy, 

where a is a constant. Draw the approximate shape of these fields .using lines of force (in the x, y plane).
