The position vector `veca` of a point (m,12) is such that `|veca|`=13, find the value of m.

If the position vector veca of a point (m,5) is such that |veca|=13 , find the value of m.

If the position vector veca of a point (m,5) is such that |veca|=13 , find the value of m.

The position vector of a point A is veca+2vecb and veca divides AB internally in the ratio 2:3 , then the position vector of the point B is -

A point P lies on a vector veca .the position vector of the point is vecr .Show that vecaxxvecr is independent of the position of the point on the vector.

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb] .

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb]

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca] xx vecb .

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb]

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb]
