If |A→×B→|=3A→⋅B→, then the value of |A→+B→| is:
1. (A2+B2+AB3)1/2
2. A+B
3. (A2+B2+3AB)1/2
4. (A2+B2+AB)1/2
Other Reason
If the angle between the vector A→ and B→ is \(\theta\), the value of the product (B→×A→)⋅A→ is equal to:
1. zero
2. BA2\(\sin\theta \cos \theta\)
3. BA2\(\cos\theta\)
4. BA2\(\sin\theta\)
