Charges are palced on the vertices of a square as shown, let E be the electric field \(\& \mathrm{~V}\) the potential at the centre, if the charges on \(A\) and \(B\) are inter changed with those on D and C respectively then.
1 \(\vec{E}\) Remain unchanged, V changes
2 Both \(\vec{E}\) and \(V\) change
3 \(\vec{E}\) and \(V\) Remains unchanged

An electromagnetic wave of frequency 3 MHz passes from vacuum into a dielectric medium with permittivity \(z=4\), then
1 Wavelength and frequency both remain unchanged
2 Wavelength is doubled and the frequency remains unchanged
3 Wavelength is doubled and the frequency becomes half
4 Wavelength is halved and the frequency remains unchanged
Explanation:
d The frequency of the e.m. waveremains same when it passes from one medium to another. Refractive of the medium, \(n=\sqrt{\frac{\Sigma}{\varepsilon_0}}=\sqrt{\frac{4}{1}}=2\) Wavelength of the electromagnetic wave in the medium \(\lambda_{\text {med }}=\frac{\lambda}{\Pi}=\frac{\lambda}{2}\)
