Solution:
In an electromagnetic wave, half of the intensity is provided by the electric field and half by the magnetic field. Hence, required ratio should be \(1: 1\)

A proton is moving with a uniform velocity of \(\$ 0 \mathrm{~ns}^{-1}\) along the \(Y\)-axis, under the joint action of a magnetic field aloig \(Z\)-axis and an electric field of magnitude \(2 \times 10 \mathrm{Vm}^{-1}\) along the negativeX-axis. If the electric field is switched off, the proton starts moving in a circle. The radius of the circle is nearly \(\left(\right.\) given \(\frac{e}{m}\) ratio for proton \(\left.=10 \mathrm{Ckg}^{-1}\right)\)
