The sum of two vectors

\mathrm{\vec A}\,and\,\mathrm{\vec B}

is at right angles to their difference. Then

View answer and explanation

Correct option: A

A = B

Option A (

A = B

) is correct because if the sum of two vectors is at right angles to their difference, it implies that the magnitudes of the two vectors are equal.
