The points

\hat{\mathbf{i}}-\hat{\mathbf{j}}+3 \hat{\mathbf{k}}

and

3 \hat{\mathbf{i}}+3 \hat{\mathbf{j}}+3 \hat{\mathbf{k}}

are equidistant from the plane

\mathbf{r}

(5 \hat{\mathbf{i}}+2 \hat{\mathbf{j}}-7 \hat{\mathbf{k}})+9=0

, then they are

View answer and explanation

Correct option: C

on the opposite sides of the plane

Option C (on the opposite sides of the plane) is correct because the perpendicular distances from the points to the plane have opposite signs, indicating they lie on opposite sides.
