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 field in a region of space is described by E = <25.0x, 0,0> (N/C). An object moves from an initial lcoation on the y-axis at y = 0.750m to a final location on the x-axis at x = 1.250m. Calculate the change in electric potential.

A charge Q=-67 nC is placed at the origin. What is the electric potential at point A=(7.1, -2.4) cm? Provide your answer in volts to the nearest integer.

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?
