Example 1 · difficulty 3/5
Six equal positive charges +q are initially placed at the vertices of a regular hexagon of circumradius R. The charge at the vertex on the positive x-axis is then removed. What is the electric field at the centre due to the five remaining charges?
- A. Zero
- B. kq/R² along the negative x-axis
- C. 5kq/R² along the positive x-axis
- D. kq/R² along the positive x-axis
