Field due to conductors and cavities

Electricity and Magnetism Level 3

Inside a neutral spherical conductor, a spherical cavity is present. A charge Q is placed inside the cavity. What is the electric field at point P.

$r_1$ , $r_2$ and $r_3$ are the distances of point P from the center of the sphere, center of the cavity and from the charge Q, respectively.

\frac{kQ}{r_1^2}

\frac{kQ}{r_2^2}

\frac{kQ}{r_3^2}

Data is insufficient

Trivial application of Faraday Cage effect Charge induced on outer surface of sphere is $+Q$ ,. Which distrbutes uniformly Subsequent electric field can be easily found

Not enough. I guess the author @Rohit Gupta should write a neat one
