Question: If two identical charges are placed 1m apart, what is the electric field at a point midway between them?

Options:

Correct Answer: 0 N/C

Solution:

The electric fields due to both charges at the midpoint cancel each other, resulting in a net electric field of 0.

If two identical charges are placed 1m apart, what is the electric field at a point midway between them?

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.

Electric Field – The electric field is a vector field around charged particles that exerts a force on other charges placed within the field.
Superposition Principle – The total electric field at a point is the vector sum of the electric fields due to individual charges.
Cancellation of Electric Fields – When two equal and opposite electric fields act at the same point, they cancel each other out, resulting in a net electric field of zero.
