A circular hole of 50 mm diameter is cut out from a uniform circular disc of 100 mm diameter, such that the hole touches the periphery of the disc. The center of gravity of the remaining section will lie:

A particle is subjected to two coplanar horizontal forces acting along the same line: a force of 2.0 kN towards the right and a force of 1.5 kN towards the left. What is the net unbalanced horizontal force acting on the particle?

For a right circular solid cone of height h, the distance of the center of gravity from the base is .
