Question:medium
If \( |\vec{a}|=13, |\vec{b}|=5 \) and \( \vec{a}\cdot\vec{b}=30 \), then \( |\vec{a}\times\vec{b}| \) is
If \( |\vec{a}|=13, |\vec{b}|=5 \) and \( \vec{a}\cdot\vec{b}=30 \), then \( |\vec{a}\times\vec{b}| \) is
Show Hint
Use identity connecting dot and cross product.

- \( 30 \)
- \( \frac{30}{25}\sqrt{233} \)
- \( \frac{30}{33}\sqrt{193} \)
- \( \frac{65}{23}\sqrt{493} \)
- \( \frac{65}{13}\sqrt{133} \)
