Practicing Success
The distance of the point (2, 1, 0) from the plane $2x + y + 2z + 5 = 0,$ is |
$\frac{10}{3}$ $\frac{5}{3}$ $\frac{10}{9}$ none of these |
$\frac{10}{3}$ |
We know that the distance of the point $(x_1, y_1, z_1)$ from the plane $ax + by + cz + d= 0 $ is $\frac{ax_1+by_1+cz_1+d}{\sqrt{a^2 + b^2 + c^2}}$ So, required distance $=\frac{|2×2+1+2×0+5|}{\sqrt{2^2 +1^2 +2^2}}=\frac{10}{3}$ |
