Question: Two forces of magnitudes $P+Q$ and $P-Q$Newton are acting at an angle of ${{135}^{o}}$. If their resultant is a force of 2 Newton perpendicular to the line of action of the second force, then

1) $P=(\sqrt{2}+1),Q=(\sqrt{2}-1)$

2) $P=(\sqrt{2}-1),Q=(\sqrt{2}+1)$

3) $P=(\sqrt{3}+1),Q=(\sqrt{3}-1)$

4) $P=(\sqrt{3}-1),Q=(\sqrt{3}+1)$

Solution:
