SUMMARY
The electric potential at point X relative to point Y can be calculated using the formula V = kQ/d, where k is Coulomb's constant, Q is the charge, and d is the distance from the charge. For a point charge of +4.7 x 10-8C, point X is 0.25m away, resulting in a potential of 1.7 x 103 V. To find the potential at point Y, the same formula applies, and the potentials can be combined as scalars, reflecting the principle that electric potentials are independent of the path taken.
