Questions & Step-by-Step Solutions

If two identical charges are placed 1m apart, what is the electric field at a point midway between them?
  • Step 1: Understand that we have two identical charges placed 1 meter apart.
  • Step 2: Identify the midpoint between the two charges, which is 0.5 meters from each charge.
  • Step 3: Recall that identical charges create electric fields that point away from each charge.
  • Step 4: Calculate the direction of the electric fields at the midpoint: both fields point in opposite directions.
  • Step 5: Since the electric fields from both charges are equal in magnitude but opposite in direction, they cancel each other out.
  • Step 6: Conclude that the net electric field at the midpoint is 0.
