Question

What is the relationship between the original vector \[\vec P\] and the new vector \[\vec Q\] = s\[\vec P\] when s = -2?

Options

• Same direction, 2 × magnitude

• Opposite direction, 2 × magnitude

• Remains Same as \[\vec P\]

• Turns into a number

Answer 1

Opposite direction, 2 × magnitude

Explanation:

Multiplying a vector by –2 flips its direction and doubles its length.
