यदि पहले खंड (OA) को गलती से (2) इकाई ले लिया जाए और (AB=1) रहे, तो पहला कर्ण क्या होगा?

If the first segment (OA) is mistakenly taken as (2) units and (AB=1), what will be the first hypotenuse?

Correct Answer

C. \(\sqrt{5}\)

Step 1

Concept

Then the hypotenuse is \(\sqrt{2^2+1^2}=\sqrt{5}\), so the standard spiral is not formed. It is necessary to start with (OA=1).

Step 2

Why this answer is correct

The correct answer is C. \(\sqrt{5}\). Then the hypotenuse is \(\sqrt{2^2+1^2}=\sqrt{5}\), so the standard spiral is not formed. It is necessary to start with (OA=1).

Step 3

Exam Tip

तब कर्ण \(\sqrt{2^2+1^2}=\sqrt{5}\) होगा, इसलिए मानक सर्पिल नहीं बनेगा। शुरुआत में (OA=1) लेना जरूरी है।
