The vector sum of two forces is perpendicular to their vector differences. In that case, the force:
Options
- Aare equal to each other
- Bare equal to each other in magnitude
- Care not equal to each other in magnitude
- Dcannot be predicted
Correct answer
B. are equal to each other in magnitude
Step-by-step solution
( A + B ) ( A - B )=0 aligned & A^2- A B + B A +B^2=0 & A = B ( A B = B A ) aligned
