If the area of a circle is 58 square feet, find the circumference. a. 4.25 ft. b. 26.99 ft. c. 42.5 ft. d. 22.35 ft.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

are there answer choices to this question? this seems like a question where you have options to choose from.
