Position vector and a vector in terms of position vectors of its end points

Components of a vector in terms of coordinates of its end points

Define position vector of point.

Define position vector of point.

If a and b are position vectors of A and B respectively the position vector of a point C on AB produced such that vec AC=3vec AB is

If a and b are the position vectors of A and B respectively; find the position vector of a point C on BA produced such that BC=3/2BA.

If a and b are position vectors of A and B respectively the position vector of a point C on AB produced such that vec(AC)=3 vec(AB) is

Define unit vector, null vector and position vector .

Position vector of the point A - position vector of the point B is -
