Given: P(1, -1, 0) and Q(2, 1, 2)
To find: Distance between given two points
Formula used:
The distance between any two points (a, b, c) and (m, n, o) is given by,
\(\sqrt{(a-m)^2+(b-n)^2+(c-0)^2}\)
Therefore,
Distance between (1, -1, 0) and (2, 1, 2) is
= \(\sqrt{(1-2)^2+(-1-1)^2+(0-2)^2}\)
= \(\sqrt{(-1)^2+(-2)^2+(-2)^2}\)
= \(\sqrt{1+4+4}\)
= \(\sqrt{9}\)
= 3
Hence, Distance between P and Q is 3 units
