Q: If two identical charges are placed 1 m apart, what will be the electric field at a point midway between them? (2019)

Solution: The electric fields due to both charges at the midpoint will cancel each other, resulting in a net electric field of 0 N/C.

Steps: 6

Step 1: Understand that we have two identical charges placed 1 meter apart.
Step 2: Identify the point of interest, which is the midpoint between the two charges (0.5 m 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 will point in opposite directions.
Step 5: Since the electric fields from both charges are equal in magnitude but opposite in direction, they will cancel each other out.
Step 6: Conclude that the net electric field at the midpoint is 0 N/C.
