Find the distance between the points P(1, -1, 0) and Q (2, 1, 2).

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,

Therefore,

Distance between (1, -1, 0) and (2, 1, 2) is

= 3

Hence, Distance between P and Q is 3 units.
