JEE Main 5 April 2024, Shift 2, Maths Q13

Question 13 of 90 in this shift, Maths question 13 of 30, Section A.

The differential equation of the family of circles passing through the origin and having centre at the line y=xy=x is :
  1. (1)(x2−y2+2xy)dx=(x2−y2−2xy)dy(x^2-y^2+2xy)dx = (x^2-y^2-2xy)dyOfficial answer
  2. (2)(x2+y2−2xy)dx=(x2+y2+2xy)dy(x^2+y^2-2xy)dx = (x^2+y^2+2xy)dy
  3. (3)(x2−y2+2xy)dx=(x2−y2+2xy)dy(x^2-y^2+2xy)dx = (x^2-y^2+2xy)dy
  4. (4)(x2+y2+2xy)dx=(x2+y2−2xy)dy(x^2+y^2+2xy)dx = (x^2+y^2-2xy)dy
