The vector sum of two forces is perpendicular to their vector differences. In that case, the forces
- A cannot be predicted
- B always are equal to each other
- C are equal to each other in magnitude
- D are not equal to each other in magnitude
Answer & Solution
Correct Answer
(C) are equal to each other in magnitude
Step-by-step Solution
Detailed explanation
Let the two forces in vector form be A→ and B→. Then their vector sum is A→+B→ and vector difference is A→-B→. As A→+B→ and A→-B→ are perpendicular to each other, thusA→+B→·A→-B→=0…
