Question: Write the magnitude of the resultant of the unit vectors j and k?
The magnitude of the resultant of the unit vectors j and k can be found using the Pythagorean theorem. Since j and k are perpendicular to each other, the magnitude of their resultant vector is equal to the square root of the sum of their squares, which is:
magnitude = sqrt(j^2 + k^2)
magnitude = sqrt(1^2 + 1^2)
magnitude = sqrt(2)
Therefore, the magnitude of the resultant vector is the square root of 2.
