The shortest distances of the point (1,2,3)(1, 2, 3) from xx, yy, zz axes respectively are

Solution

✅ Correct Option: 4

Distance from a point (x0,y0,z0)(x_0,y_0,z_0) to an axis is the square-root of the sum of squares of the other two coordinates.

From (1,2,3)(1,2,3):

  • to x-axis: 22+32=13\sqrt{2^2+3^2}=\sqrt{13}
  • to y-axis: 12+32=10\sqrt{1^2+3^2}=\sqrt{10}
  • to z-axis: 12+22=5\sqrt{1^2+2^2}=\sqrt{5}.
