🤓 Based on our data, we think this question is relevant for Professor Schulte's class at UCF.

An equilateral triangle **ABC**. A positive point charge +q is located at each of the three vertices **A**, **B**, and **C**. Each side of the triangle is of length *a*. A point charge *Q* (that may be positive or negative) is placed at the mid-point between **B** and **C**. Is it possible to choose the value of *Q* (*that is non-zero*) such that the force on *Q* is zero?

A) Yes, because the forces on *Q* are vectors and three vectors can add to zero.

B) No, because the forces on *Q* are vectors and three vectors can never add to zero.

C) Yes, because the electric force at the mid-point between **B** and **C** is zero whether a charge is placed there or not.

D) No, because the forces on *Q* due to the charges at **B** and **C** point in the same direction.

E) No, because a fourth charge would be needed to cancel the force on *Q* due to the charge at **A**.
