The vector sum of the two forces A and B is perpendicular to their vector difference. Hence forces A and B are (a) perpendicular to each other (b) unequal in magnitude (c) parallel to each other (d) equal in magnitude

Answer: (d). (A + B) · (A - B) = A² - B² = 0 So |A| = |B|: answer (d) equal in magnitude.
