Question : 4 of 90

Marks: +1, -0

Statement I Two forces (P+Q) and (P−Q) where P⊥Q, when act at an angle θ1 to each other, the magnitude of their resultant is √3(P2+Q2), when they act at an angle θ2, the magnitude of their resultant becomes √2(P2+Q2). This is possible only when θ1<θ2.
Statement II In the situation given above. θ1=60° and θ2=90°.
In the light of the above statements, choose the most appropriate answer from the options given below.
