Question: The differential equation of all circles of radius a is of order
Options:
A) 2
B) 3
C) 4
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
The equation of the family of circles of radius a is $ {{(x-h)}^{2}}+{{(y-k)}^{2}}=a^{2} $ which is a two parameter family of curves. So its differential equation is of order two.
