The radius vector and linear momentum are respectively given by vectors 2hati + hatj + hatk and 2hati - 3hatj + 3hatk Then the angular momentum is

The radius vector and linear momentum are respectively given by vector

1.	The radius vector and linear momentum are respectively given by vectors 2hati + hatj + hatk and 2hati - 3hatj + 3hatk Then the angular momentum is
Answer» `2hati - 4hatk` `4 hati- 8 hatk` `2hati - 4 hatj +2hatk` `4 hati - 8 hatj` Solution :Given radius vector , `vecr = 2 hati + hatj + hatk` Linear MOMENTUM `, VECP = 2 hati - 3hatj + hatk` As angular momentum , `VECL = vecr xx vecp = \|{:(hati , hatj , hatk) , (2 , 1 , 1) , (2 , -3 , 1):}\|` `= hati (1 - (-3)) - hatj (2 - 2) + hatk (-6 - 2) = 4 hati - 8 hatk`
