JEE Mains · Physics · STD 12 - 8. Electromagnetic waves

\(100\, MHz\) આવૃતિનું વિદ્યુતચુંબકીય તરંગ \(x -\) અક્ષ પર ગતિ કરે છે,જો ચુંબકીય ક્ષેત્ર \(\overrightarrow{ B }=2.0 \times 10^{-8} \hat{ k } T\) હોય તો વિદ્યુતક્ષેત્ર \(\overrightarrow{ E }\) શું થશે? 

  1. A \(0.6 \hat{j}\, V / m\)
  2. B \(6.0 \hat{ k }\, V / m\)
  3. C \(6.0 \hat{ j }\, V / m\)
  4. D \(0.6 \hat{ k }\, V / m\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(6.0 \hat{ j }\, V / m\)

Step-by-step Solution

Detailed explanation

\(E = BC =6\) (Dir. of wave) \(\|(\overrightarrow{ E } \times \overrightarrow{ B })\) \(\hat{ i }=\hat{ j } \times \hat{ k }\) \(\overrightarrow{ E }=6 \hat{ j } V / m\)
