Consider a point charge q = 1.4 μC, point A at distance d₁ = 3.0 m from q, and point B at distance d2 = 1.0 m. (a) If A and B are diametrically opposite each other, as in Figure (a), what is the electric potential difference VA - VB? (b) What is that electric potential difference if A and B are located as in Figure (b)?

The electric potential of a dipole is E= KQd/((d/2)2+a2))3/2 Find the electric potential V by integrating the elctric field

The electric potential V in a region of space is given by V(x, y, z) = A(x² – 3y² + z?) where A = 4.00x103 J/(C-m²). a) What is the electric field at the point (1.00 m, 1.00 m, 1.00 m)? b) If an 8.854 x 10-12 kg test charge of +1.50 µC were placed at the point (0, 0, 1.00 m) and released from rest, will it move toward the origin or away from the origin? Explain. c) After starting from rest at the point (0, 0, 1.00 m), what will be the speed of the test charge after it has traveled 1.00 m along the z-axis?

At a distance of 0.40 m from a proton, calculate its electric field strength. At this distance, what is the electric potential?
