Given two vectors veca=-hati + 2hatj + 2hatk and vecb =- 2hati + hatj + 2hatk |
|
Answer» <P> b. `vecaxxvecb=|{:(hati,hatj,HATK),(-1,2,2),(-2,1,2):}|` `2hati-2hatj+3hatk` c. if `vecc` is equally inclined to `veca and vecb` , then we must have `veca.vecc= vecb.vecc`. which is true for vectors in options p,q,s d. vector is forming a TRIANGLE with `veca and vecb`. THUS `vecc= veca + vecb = -3hati + 3hatj + 4hatk` |
