The weight Mg of an extended body is generally shown in a diagram to act through the centre of mass. Does it mean that the earth does not attract other particles?

find moment of inertia about an axis yy which passes through the centre of mass of the two particle system as shown

The centre of mass of an extended body on the surface of the earth and its centre of gravity

For which of the following does the centre of mass lie outside the body ?

For which of the following does the centre of mass lie outside the body ?

For which of the following does the centre of mass lie outside the body ?

Why does a body lose weight at the centre of the earth?

The position of centre of mass of system of particles at any moment does not depend on.

A particle of mass m is thrown upwards from the surface of the earth, with a velocity u . The mass and the radius of the earth are, respectively, M and R . G is gravitational constant g is acceleration due to gravity on the surface of earth. The minimum value of u so that the particle does not return back to earth is

With what minimum velocity v should a particle be thrown horizontally from a height h above the surface of the earth of mass M so that it does not fall back on the earth ? Radius of earth is R ?

Let I_(A) and I_(B) be moments of inertia of a body about two axes A and B respectively. The axis A passes through the centre of massof the body but B does not. Choose the correct option.
