Potential due to point-charges: Four equal +6.00-μC point charges are placed at the corners of a square 2.00 m on each side. (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2) (a) What is the electric potential (relative to infinity) due to these charges at the center of this square? (b) What is the magnitude of the electric field due to these charges at the center of the square?

Electric field of a single point-charge: The electric field  1.5 cm from a very small charged object points toward the object with a magnitude of 180,000 N/C. What is the charge on the object? (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)
