Question

A vector is not changed if ______.

Options

• it is divided by a scalar

• it is multiplied by a scalar

• it slides parallel to itself

• all of these

Answer 1

A vector is not changed if it slides parallel to itself.

Explanation:

A vector is defined by its magnitude and direction only, sliding it parallel to itself (translation) doesn't change either, so the vector remains unchanged; but dividing or multiplying by a scalar changes its magnitude.
