In an ac generator, a rectangular coil of \(100\) turns each having area \(14 \times 10^{-2}\,m ^2\) is rotated at \(360\,rev / min\) about an axis perpendicular to a uniform magnetic field of magnitude \(3.0 T\). The maximum value of the emf produced will be \(............V\). \(\left(\right.\) Take \(\left.\pi=\frac{22}{7}\right)\)
- A \(1583\)
- B \(1528\)
- C \(1584\)
- D \(1580\)
Answer & Solution
Correct Answer
(C) \(1584\)
Step-by-step Solution
Detailed explanation
\(\varepsilon_{\max }= NAB \omega\) \(=100 \times 14 \times 10^{-2} \times 3 \times \frac{360 \times 2 \pi}{60}\) \(=1584\,V\)

- The box of a pin hole camera, of length \(L\), has a hole of radius \(a\). It is assumed that when the hole is illuminated by a parallel beam of light of wavelength \(\lambda\), the spread of the spot (obtained on the opposite wall of the camera) is the sum of its geometrical spread and the spread due to diffraction. The spot would then have its minimum size ( say \(b_{min}\)) whenJEE Mains 2016 Hard
