Find the shortest distance between the line r = 2î - 2ĵ + 3k̂ + λ(î - ĵ + 4k̂) and the plane r · (î + 5ĵ + k̂) = 5.

  1. (10)/(9)
  2. (10)/(3√(3))
  3. (3)/(10)
  4. (10)/(3)

Correct answer: (10)/(3√(3))

Solution

The shortest distance from a line to a plane is found by projecting a vector from a point on the line to the plane along the direction normal to the plane. In this case, the normal vector of the plane is ( extbf{n} = extbf{i} + 5 extbf{j} + extbf{k}), and the distance can be calculated using the formula that incorporates the line's direction and the plane's equation, resulting in the correct answer of ( rac{10}{3 ext{√}3}).
