### Question

Seven identical coins are rigidly arranged on a flat table in the pattern shown below so that each coin touches its neighbors. Each coin is a thin disc of mass m and radius r. Note that the moment of inertia of an individual coin about an axis passing through center and perpendicular to the plane of the coin is.

The moment of inertia of the system of seven coins about an axis that passes through the point P (the centre of the coin positioned directly to the right of the central coin) and perpendicular to the plane of the coins is-

### Question

The moments of inertia of a non – uniform circular disc (of mass M and radius R) about four mutually perpendicular tangents AB, BC, CD, DA are I1, I2, I3 and I4, respectively (the square ABCD circumscribes the circle). The distance of the centre of mass of the disc from its geometrical centre is given by,
