Question: If two identical charges are placed at a distance of 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 N/C.

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

Step 1: Understand that we have two identical charges, which means they have the same type of charge (both positive or both negative).
Step 2: Place the two charges 1 meter apart. This means the distance from each charge to the midpoint is 0.5 meters.
Step 3: At the midpoint, we need to find the electric field created by each charge.
Step 4: The electric field created by a positive charge points away from the charge, while the electric field created by a negative charge points towards the charge.
Step 5: Since both charges are identical and of the same type, the electric field from each charge at the midpoint will point in opposite directions.
Step 6: Because the electric fields from both charges are equal in strength but opposite in direction, they will cancel each other out.
Step 7: Therefore, the net electric field at the midpoint between the two charges is 0 N/C.

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 identical charges are equidistant from a point, their electric fields at that point can cancel each other out.
