A$.$ Camera mounted in the origin of Cartesian coerdinate, its view is perpendicular an z$-$axis and it passes in its center. The view port has size $55$ unit and $1$ unit far from the erigin. If there is sphere has radius of $5$ units and its origin at $(1,3,10).$ Get the value of t$\text{'}$s cerresponding to the intersection of the ray passing through the center of the viewport $($i$.$e$,$ point $0,0,1).($Give the equations and then apply to get the intersection$).$
