એક વિદ્યુતચુંબકીય તરંગ માટે ચુંબકીયક્ષેત્ર \(\overrightarrow{\mathrm{B}}=3 \times 10^{-8} \sin \left(1.6 \times 10^{3} \mathrm{x}+48 \times 10^{10} \mathrm{t}\right) \hat{\mathrm{j}}\; \mathrm{T}\) મુજબ આપવામાં આવે તો તેના માટે વિદ્યુતક્ષેત્ર કેટલું હોવું જોઈએ?

1. A \(\overrightarrow{\mathrm{E}}=\left(9 \sin \left(1.6 \times 10^{3} \mathrm{x}+48 \times 10^{10} \mathrm{t}\right) \hat{\mathrm{k}} \;\mathrm{V} / \mathrm{m}\right)\)
2. B \(\left.\overrightarrow{\mathrm{E}}=\left(3 \times 10^{-8} \sin \left(1.6 \times 10^{3} \mathrm{x}+48 \times 10^{10} \mathrm{t}\right)\right) \hat{\mathrm{i}}\; \mathrm{V} / \mathrm{m}\right)\)
3. C \(\overrightarrow{\mathrm{E}}=\left(60 \sin \left(1.6 \times 10^{3} \mathrm{x}+48 \times 10^{10} \mathrm{t}\right) \hat{\mathrm{k}}\; \mathrm{V} / \mathrm{m}\right)\)
4. D \(\overrightarrow{\mathrm{E}}=\left(3 \times 10^{-8} \sin \left(1.6 \times 10^{3} \mathrm{x}+48 \times 10^{10} \mathrm{t}\right) \hat{\mathrm{j}} \;\mathrm{V} / \mathrm{m}\right)\)
