Q. Consider a sphere of radius $R$ with unform charged density and total charge Q. The electrostatic potential distribution inside the sphere is given by $\phi( r )=\frac{ Q }{4 \pi \varepsilon_{0} R }\left( a + b ( r / R )^{ c }\right)$. Note that the zero of potential is at infinity. The values of $(a, b, c)$ are :-
