Points A (3 m, 6 m) and B (6 m, -3 m) are in a region where the electric field is uniform and given by E = 12 N/C in the positive x direction. What is the electric potential difference VA – VB?

Suppose that three astronomical objects, 1, 2, and 3 are observed to lie on a line, and the distance from object 1 to object 3 is d. object 1 has four times the mass of object 3, and seven times the mass of object 2. find the distance between objects 1 and 2 for which the net force on object 2 is zero.
