Two positive point charges +4.00 μC and +2.00 μC are placed at the opposite corners of a rectangle as shown in the figure. (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2) 
(a) What is the potential at point A (relative to infinity) due to these charges?
(b) What is the potential at point B (relative to infinity) due to these charges?
Definitions:
FSH Secretion
Refers to the release of Follicle-Stimulating Hormone by the anterior pituitary gland, which plays a key role in the regulation of growth, reproduction, and pubertal development.
LH Secretion
The release of luteinizing hormone, a key hormone in the regulation of the reproductive system.
Puberty
The developmental stage in humans and other animals during which adolescents mature sexually and become capable of reproduction.
GnRH Levels
Refers to the concentration of Gonadotropin-Releasing Hormone, a pivotal hormone in the reproductive system that stimulates the release of sex hormones.
