The vectors sum of two forces is perpendicular to their vector differences in that case. The forces

View answer and explanation

Correct option: B

Are equal to each other in magnitude

Option B (Are equal to each other in magnitude) is correct because if the vector sum is perpendicular to the vector difference, the dot product of the sum and difference is zero, implying equal magnitudes.
