What is the electric field at a point midway between two equal and opposite charges?
Correct Answer: Zero electric field
Step 1: Identify the two charges. Let's call them Charge A (positive) and Charge B (negative).
Step 2: Place Charge A and Charge B an equal distance apart.
Step 3: Find the midpoint between Charge A and Charge B. This is the point we are interested in.
Step 4: Understand that electric fields point away from positive charges and towards negative charges.
Step 5: At the midpoint, the electric field from Charge A points away from it (to the right) and the electric field from Charge B points towards it (to the right as well).
Step 6: Since the magnitudes of the electric fields from both charges are equal but in opposite directions, they cancel each other out.
Step 7: Therefore, the total electric field at the midpoint is zero.
