In the first configuration (1) as shown in the figure, four identical charges \( q_0 \) are kept at the corners A, B, C and D of square of side length \( a \). In the second configuration (2), the same charges are shifted to mid points C, E, H, and F of the square. If \( K = \frac{1}{4\pi \epsilon_0} \), the difference between the potential energies of configuration (2) and (1) is given by:

Show Hint
- \( \frac{Kq_0^2}{a} (4\sqrt{2} - 2) \)
- \( \frac{Kq_0^2}{a} (4 - \sqrt{2}) \)
- \( \frac{Kq_0^2}{a} (3\sqrt{2} - 2) \)
- \( \frac{Kq_0^2}{a} (3 - \sqrt{2}) \)
The Correct Option is A

Top Questions on Electromagnetic Field (EMF)
A proton is moving undeflected in a region of crossed electric and magnetic fields at a constant speed of \( 2 \times 10^5 \, \text{m/s} \). When the electric field is switched off, the proton moves along a circular path of radius 2 cm. The magnitude of electric field is \( x \times 10^4 \, \text{N/C} \). The value of \( x \) is \(\_\_\_\_\_\). (Take the mass of the proton as \( 1.6 \times 10^{-27} \, \text{kg} \)).
