Final answer:
To find the magnitude of the vector formed by Bx and By, use the Pythagorean theorem.
Step-by-step explanation:
To find the magnitude of the vector formed by Bx and By, we can use the Pythagorean theorem. The magnitude of a vector is found by taking the square root of the sum of the squares of its components.
In this case, the magnitude of the vector can be found using the equation:
magnitude = sqrt(Bx^2 + By^2).
Plugging in the given values, we get:
magnitude = sqrt((-1.33m)^2 + (2.81m)^2).
Calculating this, we find that the magnitude of the vector is approximately 3.20m.
