Challenge Problems
Push your limits with challenges.
Question 1
A point charge of +5 ΞΌC is located at the origin. Calculate the electric field strength at a point 3 meters away and determine the direction of the field.
π‘ Hint: Apply the formula correctly and clarify the direction based on the charge sign.
Question 2
Two equal point charges of +2 ΞΌC are placed 1 meter apart. What is the electric field strength at a point halfway between the two charges?
π‘ Hint: Analyze the contributions from each charge based on distance and construct a combined field.
