The order of the differential equation of all circles which lie in the first quadrant and touch both the axes is…

  • A
    Two
  • B
    Three
  • Correct answer
    C
    One
  • D
    Four

Solution

Equation of the circle touching both axes is x2+y2-2ax-2ay+a2=0
Here, number of arbitrary constant is one which is equal to the order of its differential equation.

Hence, the correct answer is option: 'C'.
