Answer: The magnitude of the magnetic component is 0.7nT
Explanation: Please see the attachments below
Answer:
7 units, north
Explanation:
This is a problem of vector subtraction. We have:
- Vector A: magnitude 2 units, direction to the north
- Vector B: magnitude 5 units, direction to the south
If we take the north as positive direction, we can write
Since we want to find (vector subtraction), we have to change the sign of B, so we find:
And the positive sign means the direction is north.
