\( \hat{k} \times \hat{j} = \hat{i} \)

প্রশ্ন: \( \hat{k} \times \hat{j} = \hat{i} \)

উত্তর: \( \hat{k} \times \hat{j} = -\hat{i} \)

ব্যাখ্যা:

• \(\hat{i} \times \hat{j} = \hat{k}\)
• \(\hat{j} \times \hat{k} = \hat{i}\)
• \(\hat{k} \times \hat{i} = \hat{j}\)

• \(\hat{j} \times \hat{i} = -\hat{k}\)
• \(\hat{k} \times \hat{j} = -\hat{i}\)
• \(\hat{i} \times \hat{k} = -\hat{j}\)

অতএব, প্রদত্ত উত্তরটি ভুল। ❌

সঠিক উত্তর: \( \hat{k} \times \hat{j} = -\hat{i} \) ✅
