Find the scalar and vector products of two vectors. a = (3hati – 4hatj + 5hatk) and b = (– 2hati + hatj – 3hatk )

Find the scalar and vector products of two vectors. a = (3hati – 4ha

1.	Find the scalar and vector products of two vectors. a = (3hati – 4hatj + 5hatk) and b = (– 2hati + hatj – 3hatk )
Answer» Solution :`a.b=(3hati-4hatj+5hatk).(-2hati+hatj-3hatk)` `=-6-4-15` `=-25` `axxb=\|(HATI,hatj,hatk),(3,-4,5),(-2,1,-3)\|=7hati-hatj-5hatk` NOTE `bxxa=-7hati+hatj+5hatk`
