If the points `(1,\ 1,\ lambda)a n d\ (-3,\ 0,\ 1)` be equidistant from the plant ` vec rdot((3 hat i+4 hat j-12 hat k)+13=0` find the value of `lambdadot`

Explanation

`overline{{r}}(-3 hat{{i}}-4 hat{{j}}+12 hat{{k}})=13`


`d=13`

Magnitude of `overline (n) = sqrt((-3)^2 +(-4)^2 + 12^2)`

`Rightarrow |overline n| = sqrt ( 9 + 16 + 144)`

`= sqrt 169`

`=13`
