Question: The locus of centre of a circle passing through (a, b) and cuts orthogonally to circle ${{x}^{2}}+{{y}^{2}}={{p}^{2}}$ , is

1) $2ax+2by-({{a}^{2}}+{{b}^{2}}+{{p}^{2}})=0$

2) $2ax+2by-({{a}^{2}}-{{b}^{2}}+{{p}^{2}})=0$

3) ${{x}^{2}}+{{y}^{2}}-3ax-4by+({{a}^{2}}+{{b}^{2}}-{{p}^{2}})=0$

4) ${{x}^{2}}+{{y}^{2}}-2ax-3by+({{a}^{2}}-{{b}^{2}}-{{p}^{2}})=0$
