Nitu and Milan sat for a Competitive examination on a science subject today. There were 12 questions in the question paper. 6 marks was allotted for each correct answer and 3 marks for each wrong answer. Nitu had 7 correct answers and got 5 answers wrong.

In the given figure, name (i) any six points (ii) any five line segments (iii) any four rays (iv) any four lines (v) any four collinear points

The position vecors of the points A and B are 4hat(i)-3hat(j)+5hat(k) " and " -2hat(i)+3hat(j)+2hat(k) respectively, find (i) the position vector of the middle point of the line-segment bar(AB) , (ii) the position vector of the points of trisection of the line-segment bar(AB) .

If vec(a)=4vec(i)-3hat(j) " and " vec(b)=-2hat(i)+5hat(j) are the position vectors of the points A and B respectively, find (i) the position vector of the middle point of the line-segment bar(AB) , (ii) the position vectors of the points of trisection of the line-segment bar(AB) .

P is a veriable poin on the hyperbola x^(2) - y^(2) =16 and A (8,0) is a fixed point . Show that the locus of the middle point of the line segment bar(AP) is another rectangular hyperbola.
