Let `vecr` be a position vector of a variable point in Cartesian OXY plane such that `vecr. ( 10 hatj - 8 hati-vecr) =40` and `P_(1)=max {|vecr+2hati - 3hatj|^(2)} , P_(2) = min {|vecr+ 2hati - 3 hatj|^(2)}` . A tangenty line is drawn to the curve `y= 8// x^(2)` at point .A with abscissa 2. the drawn line cuts the x-axis at a point B.
