প্রশ্ন: \(\hat{j}+\hat{k}\) × \(\hat{k}\) = ?
সমাধান:
আমরা জানি,
- \(\hat{i}\) × \(\hat{j}\) = \(\hat{k}\)
- \(\hat{j}\) × \(\hat{k}\) = \(\hat{i}\)
- \(\hat{k}\) × \(\hat{i}\) = \(\hat{j}\)
- \(\hat{i}\) × \(\hat{i}\) = \(\vec{0}\)
- \(\hat{j}\) × \(\hat{j}\) = \(\vec{0}\)
- \(\hat{k}\) × \(\hat{k}\) = \(\vec{0}\)
এখন, (\(\hat{j}+\hat{k}\)) × \(\hat{k}\) = \(\hat{j}\) × \(\hat{k}\) + \(\hat{k}\) × \(\hat{k}\) 🤓
= \(\hat{i}\) + \(\vec{0}\) 🎉
= \(\hat{i}\) ✅
অতএব, (\(\hat{j}+\hat{k}\)) × \(\hat{k}\) = \(\hat{i}\) 😊
