Question

Three equal charges (\( q \)) are placed at corners of an equilateral triangle of side \( a \). The force on any charge is â

• A. zero
• B. \( \sqrt{3} \frac{Kq^2}{a^2} \)
• C. \( \frac{Kq^2}{\sqrt{3} a^2} \)
• D. \( 3 \sqrt{3} \frac{Kq^2}{a^2} \)

Hint:

In an equilateral triangle, the resultant force on any charge can be calculated by vector addition of the forces from the other two charges.

Answer 1
