If three forces P, Q, and R keep a body in equilibrium, the angle between P and Q is 90° and R is acting vertically downward, then the magnitude of forces R and Q respectively in terms of P will be
1
\(\frac{P}{{\sqrt 2 }},\;\sqrt 2 P\)
2
\(\sqrt 2 P,\frac{P}{{\sqrt 2 }}\)
3
\(P,\;\sqrt 2 P\)
4
\(P,\;2 P\)
5
\(\sqrt 2 P,\;P\)
