    The equation of the circle is, (x – h)2 + (y – k)2 = r2 ….(i) Since the circle passes through point (2, 3) ∴ (2 – h)2 + (3 – k)2 = r2 ⇒ 4 + h2 – 4h + 9 + k2 – 6k = r2 ⇒ h2+ k2 – 4h – 6k + 13 = r2 ….(ii) Also, the circle passes through point (-1, 1) ∴ (-1 – h)2 + (1 – k)2 = r2 ⇒ 1 + h2 + 2h + 1 + k2 – 2k = r2 ⇒ h2 + k2 + 2h – 2k + 2 = r2 ….(iii) From (ii) and (iii), we have h2 + k2 – 4h – 6k + 13 = h2 + k2 + 2h – 2k + 2 ⇒ -6h – 4k = -11 ⇒ 6h + 4k = 11 …(iv) Since the centre (h, k) of the circle lies on the line x – 3y-11 = 0. ∴ h – 3k – 11 = 0 ⇒ h -3k = 11 …(v) Solving (iv) and (v), we get h = \frac { 7 }{ 2 } and k = \frac { -5 }{ 2 } Putting these values of h and k in (ii), we get \left( \frac { 7 }{ 2 } \right) ^{ 2 }+\left( \frac { -5 }{ 2 } \right) ^{ 2 }-\frac { 4\times 7 }{ 2 } -6\times \frac { -5 }{ 2 } +13={ r }^{ 2 } ⇒ \frac { 49 }{ 4 } +\frac { 25 }{ 4 } -14+15+13 ⇒ { r }^{ 2 }=\frac { 65 }{ 2 } Thus required equation of circle is ⇒ \left( x-\frac { 7 }{ 2 } \right) ^{ 2 }+\left( y+\frac { 5 }{ 2 } \right) ^{ 2 }=\frac { 65 }{ 2 } ⇒ { x }^{ 2 }+\frac { 49 }{ 4 } -7x+{ y }^{ 2 }+\frac { 25 }{ 4 } +5y=\frac { 65 }{ 2 } ⇒ 4x2 + 49 – 28x + 4y2 + 25 + 20y = 130 ⇒ 4x2 + 4y2 – 28x + 20y – 56 = 0 ⇒ 4(x2 + y2 – 7x + 5y -14) = 0 ⇒ x2 + y2 – 7x + 5y -14 = 0.

    The title ‘Ailing Planet’ is aptly justified. Nani Palkhiwala, the author brings our attention towards the critical condition of our planet, Earth. Man’s recklessness, greed and indifference to the needs of the planet, have literally made its condition exactly like a patient needing immediate treatment. The illness of pollution has reached its final stage. If the intensive care treatment is not given to it, it may collapse I think its help you my dear friend
