MCQ
The distance between the points $A(0, 6)$ and $B(0, -2)$ is :
  • A
    $6$
  • $8$
  • C
    $4$
  • D
    $2$

Answer

Correct option: B.
$8$
$V$ distance between the points $\left(x_1, y_1\right),\left(x_2, y_2\right)$
$\text{d}=\sqrt{(\text{x}_2-\text{x}_1)^2+(\text{y}_2-\text{y}_1)^2}$
Here, $\mathrm{x}_1=0, \mathrm{y}_1=6$ and $\mathrm{x}_2=0, \mathrm{y}_2=-2$
Distance between $A(0, 6)$ and $B(0, -2),$
$\text{AB}=\sqrt{(0-0)^2+(-2-6)^2}$
$\text{AB}=\sqrt{0+(-8)^2}$
$\text{AB}=\sqrt{8^2}$
$\text{AB}=8$
