Statement I Two forces (P+Q) and (P-Q) where

P \bot Q

, when act at an angle

{\theta _1}

to each other, the magnitude of their resultant is

\sqrt {3({P^2} + {Q^2})} ,

when they act at an angle

{\theta _2},

the magnitude of their resultant becomes

\sqrt {2({P^2} + {Q^2})}

. This is possible only when

{\theta _1} < {\theta _2}.

Statement II In the situation given above.

{\theta _1} = {60^ \circ }\,\,\mathrm{and}\,\,{\theta _2} = {90^ \circ }

In the light of the above statements, choose the most appropriate answer from the options given below.

View answer and explanation

Correct option: B

Both Statement I and Statement II are true

Option B (Both Statement I and Statement II are true) is correct because both statements accurately describe the resultant of two forces P+Q and P-Q under given conditions.
