1.	If vecA=3hati+4hatj"and"vecB=7hati+24hatj, find a vector having the same magnitude as vecBand parallel to vecA
Answer» SOLUTION :The vector parallel to `VECA `and having magnitude of `vecB" is "vecC=\|vecB\|vecA/\|vecA\|=\|vecB\|hatA` `B=SQRT(7^(2)+24^(2))=25"and"hatA=hatA/A=(3hati+4hatj)/sqrt(3^(2)+4^(2))=1/5(3hati+4hatj)` `vecC=25xx1/5(3hati+4hatj)=15hati+20hatj`
