Step 1: Analyze [Co(NH₃)₆]³⁺
In this complex, Co³⁺ is in a strong field provided by NH₃ (a strong ligand). The strong field causes the pairing of electrons, making the complex diamagnetic.
Step 2: Analyze [CoF₆]³⁻
In this complex, Co³⁺ is in a weak field provided by F⁻ (a weak ligand). The weak field does not cause pairing of electrons, making the complex paramagnetic.
Step 3: Conclude the Statements
Conclusion
The correct analysis of the magnetic behavior of the complexes confirms that:
Both Statement I and Statement II are true.Step 1: Analyze [Co(NH₃)₆]³⁺

Given below are two statements:
Statement I: Ferromagnetism is considered as an extreme form of paramagnetism.
Statement II: The number of unpaired electrons in a $Cr^{2+}$ ion (Z = 24) is the same as that of a $Nd^{3+}$ ion (Z = 60).
In the light of the above statements, choose the correct answer from the options given below:
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A full wave rectifier circuit with diodes (\(D_1\)) and (\(D_2\)) is shown in the figure. If input supply voltage \(V_{in} = 220 \sin(100 \pi t)\) volt, then at \(t = 15\) msec:
