Writhe the component of ` vec b` along ` vec adot`

If vec(A)=2hat(i)+hat(j) and vec(B)=hat(i)-hat(j) , sketch vector graphically and find the component of vec(A) along vec(B) and perpendicular to vec(B)

If vec a\ a n d\ vec b are two vectors such that vec adot vec b=6,\ | vec a|=3\ a n d\ | vec b|=4. Write the projection of vec a\ on\ vec bdot

What is the component of the vector vec(a) along the x-axis in the situation shown in figure ? |vec(a)| = 5 units.

If vec(A)=2hati+hatj+hatk " and " vecB=10hati+5hatj+5hatk , if the magnitude of component of (vec(B)-vec(A)) along vec(A) is 4sqrt(x) . Then x will be .

If vec a and vec b are two collinear vectors, then which of the following are incorrect:(A) vec b=lambda vec a , for some scalar lambda (B) vec a=+- vec b (C) the respective components of vec a and vec b are proportional(D) both the vectors vec a and vec b have same direction, but different magnitudes.

If | vec a|=2,\ | vec b|=3\ a n d\ vec adot vec b=3 find the projection of vec b\ on\ vec adot

If vec a\ a n d\ vec b are unit vectors then write the value of | vec axx vec b|^2+( vec adot vec b)^2dot

If vec a\ a n d\ vec b are unit vectors then write the value of | vec axx vec b|^2+( vec adot vec b)^2dot

If vec a= hat i+ hat j+ hat k , vec b= hat i- hat j+ hat k , vec c= hat i+2 hat j- hat k , then find the vaue of | vec adot vec a vec adot vec b vec adot vec c vec bdot vec a vec bdot vec a vec bdot vec a dot vec c dot vec a dot vec c dot vec a dot vec c dot vec a| .
