यदि vecA=hati+hatj-hatk तथा vecB=2hati+3hatj+phatk परस्पर लंबवत सदिश हैं तो p का मान ज्ञात कीजिए...

If vecA = hati+hatj+hatk and vecB = 2hati+hatj find vecA . vecB

If veca=3hati+hatj-4hatk and vecb=6hati+5hatj-2hatk find |veca Xvecb|

If veca=2hati-3hatj-hatk and vecb=hati+4hatj-2hatk , then vecaxxvecb is

If veca = 2hati -3hatk and vecb =hati + 4hatj -2hatk " then " veca xx vecb is

If vecA=5hati-2hatj+3hatk and vecB=2hati+hatj+2hatk , component of vecB along vecA is

If vecA=2hati+3hatj-hatk and vecB=-hati+3hatj+4hatk then projection of vecA on vecB will be

If vecA=3hati+hatj+2hatk and vecB=2hati-2hatj+4hatk , then value of |vecA+vecB| will be

If veca =hati + hatj - hatk, vecb = 2hati + 3hatj + hatk and vec c = hati + alpha hatj are coplanar vector , then the value of alpha is :

Let veca= 2 hati + 3hatj - 6hatk, vecb = 2hati - 3hatj + 6hatk and vecc = -2 hati + 3hatj + 6hatk . Let veca_(1) be the projection of veca on vecb and veca_(2) be the projection of veca_(1) on vecc . Then veca_(1).vecb is equal to
