यदि \(OB=\sqrt{2}\) और (BC=1) को (OB) पर लंब खींचा गया है, तो (OC) की लंबाई क्या होगी?
If \(OB=\sqrt{2}\) and (BC=1) is drawn perpendicular to (OB), what is the length of (OC)?
Explanation opens after your attempt
C. \(\sqrt{3}\)
Concept
Here (OC-2=\(\sqrt{2}\)2+12=3), so \(OC=\sqrt{3}\). At each new step, (1) is added to the previous square under the root.
Why this answer is correct
The correct answer is C. \(\sqrt{3}\). Here (OC-2=\(\sqrt{2}\)2+12=3), so \(OC=\sqrt{3}\). At each new step, (1) is added to the previous square under the root.
Exam Tip
यहां (OC-2=\(\sqrt{2}\)2+12=3), इसलिए \(OC=\sqrt{3}\)। हर नए चरण में पिछले वर्गमूल में (1) जोड़ा जाता है।
