• B. $ x $
• C. $ x $
• D. $ x $

Answer 1

Answer: (B)

Let $ R=1\Omega $ and $ 6.33\times {{10}^{-5}}J $ be two lines whose combined equation is $ 2\Omega $ Then, $ 2\Omega $ and $ 0.5\Omega $ Given, $ 1\Omega $ Then, $ 4\Omega $ and $ \frac{M{{R}^{2}}T}{2\pi } $ $ \frac{M{{R}^{2}}T}{4\pi } $ $ \frac{4\pi M{{R}^{2}}}{5T} $ and $ \frac{2\pi M{{R}^{2}}}{5T} $ $ U(X)=\left[ \frac{{{x}^{4}}}{4}-\frac{{{x}^{2}}}{2} \right]J $ $ \sqrt{2} $ $ \frac{1}{\sqrt{2}} $ $ \frac{3}{\sqrt{2}} $ $ \frac{45}{8}km/h $ $ \frac{25}{4}km/h $
