JEE Math Practice Question
The differential equation of the family of circles with fixed radius $$5$$ units and centre on the line $$y = 2$$ is :
- A.$$\left( {x - 2} \right){y^2} = 25 - {\left( {y - 2} \right)^2}$$
- B.$$\left( {y - 2} \right){y^2} = 25 - {\left( {y - 2} \right)^2}$$
- C.$${\left( {y - 2} \right)^2}{y^2} = 25 - {\left( {y - 2} \right)^2}$$
- D.$${\left( {x - 2} \right)^2}{y^2} = 25 - {\left( {y - 2} \right)^2}$$
