## Practice MCAT Question - Q25 - Answer!

**In the figure below, points A, B, and C are at various distances from a given point**

**charge.**

**Which statement is most accurate? The electric field strength is**

**A.**greatest at point A.

**B.**greatest at point B.

**C.**greatest at point C.

**D.**the same at all three points.

*The correct answer is (C). From Coulomb’s law, force varies inversely with the square of the distance from the charge. The strength of the electric field at a point is the ratio of this force to the charge:*

*E = F/q = (k(q*

_{1}q_{2})/r^{2})/q

*Therefore, E and r*

^{2}are inversely proportional. The smaller the value of r, the smaller the value of r^{2}and the greater the value of E.**Check The Sidebar For Another**
