The electric potential at large distances from the dipole (i.e. ligand >> d) is described by the relationship V (r, α) = kQ? ∙ cosα?2, where d is the distance between the charges of the dipole and r is the distance from the dipole center. In the Cartesian system whose beginning is halfway between the charges of the dipole, and the axis of the dipole is the X axis (see figure), and limited to the two-dimensional case, the given relationship is as follows:V (x, y) = k ∙ Q? ∙ x / (x2 + y2) 3/2Using this relationship, determine the coordinates of the electric field intensity vector at the point with the coordinates P = (R, R), i.e. at any point lying on the straight line lying at the angle α = π / 4 at a distance of √2 ∙ R from the origin of the coordinate system, at a large distance from the origin coordinate system.
Consider two negative charges, -/q/ and -/3q/, held fixed at the base of an equilateral triangel of side length s. The remaining vertex of the triangle is point P. Let q = -1.00 nC, and s = 6.00 cm. (C.) How much work will it take (similarly, what will be the change in the electric potential energy of the system) to bring a third negative charge (-/q/) to point P from a very large distance away? (D.) If the third charged particle (-/q/) is placed at point P, but not held fixed, it will experience a repellent force and accelerate away from the other two charges. If the mass of the third particle is m = 6.50 10-12 kg, what will the speed of this charged particle be once it has moved a very large distance away?
