Do the rollowing exercise:

We want to make an arrow represent the relative position vector of the tennis ball with respect to the cricket ball. That is$,$ the arrow's tail should be at the position of the cricket ball $($the white sphere$),$ and the tip should be at the position of the tennis ball $($the green sphere$).$

sphere $($pos$=$vector $(2,4,0),$ radius $=0\mathrm{.}20,$ color $=$color. whi

sphere$($pos$=$vector $(-3,-1,0),$ radius $=0\mathrm{.}3,$ color $=$ color. $gr$

arrow pos $=$vector$(2,-3,0),$ axis$=$vector $(3,4,0),$ color$-$co

$11.$

What would be the pos of this arrow, whose tail is on the cricket ball $($the white sphere$)?$

What would be the axis of this arrow, so that the tip is on the tennis ball $($the green sphere$)?$

Using these values of pos and axis, change the last line of the program to make the red arrow point from the white cricket ball to the green tennis ball.

Run the program.

Self check: Examine the $3$D display carefully. If the red arrow does not point from the white cricket ball to the green tennis ball, correct your program.
