Questions & Step-by-Step Solutions
What happens to the electric field if the charge is tripled while keeping the distance constant?
Step 1: Understand that the electric field (E) is created by a charge (Q).
Step 2: Know that the formula for the electric field due to a point charge is E = k * Q / r^2, where k is a constant and r is the distance from the charge.
Step 3: Recognize that if we keep the distance (r) constant and only change the charge (Q), the electric field depends only on the charge.
Step 4: If the charge is tripled (Q becomes 3Q), we can substitute this into the formula: E = k * (3Q) / r^2.
Step 5: This shows that the new electric field (E') is E' = 3 * (k * Q / r^2), which means the electric field is now three times larger.
Step 6: Conclude that tripling the charge while keeping the distance constant will triple the electric field.
