Define position vector of point.

(A) : When the observation point lies along the length of the current element, magnetic field is zero. (R) : According to Biot-Savart's law field is defined only when position vector of a point relative to current element is non zero.

If position vector of points A,B and C are respectively hati,hatj, and hatk and AB=CX , then position vector of point X is

If vec a and vec b are position vectors of points A and B respectively,then find the position vector of points of trisection of AB

If vec a and vec b are position vectors of points Aa n dB respectively, then find the position vector of points of trisection of A B .

If veca and vecb are position vectors of the points A and B respectively, then position vector of a point C in AB produced such that AC = 3AB is :

If position vector of points A,B and C are respectively hati,hatj, and hatk and AB=CX , then position vector of point X is

If position vector of points A,B and C are respectively hati,hatj, and hatk and AB=CX , then position vector of point X is

If position vector of points A,B and C are respectively hati,hatj, and hatk and AB=CX , then position vector of point X is

If position vector of points A,B and C are respectively hati,hatj, and hatk and AB=CX , then position vector of point X is
