Challenge Problems

Push your limits with challenges.

Question 1

Consider three charges: +3 μC, -3 μC, and +1 μC positioned at the vertices of an equilateral triangle. Compute the electric field at the centroid of the triangle.

💡 Hint: Utilize the principles of symmetry and vector addition to simplify your calculations.

Question 2

A charged rod creates a non-uniform electric field around it. Formulate a problem to determine the electric field strength at varying distances from the rod's ends.

💡 Hint: Remember that strength varies inversely with the square of the distance from a point charge.
