WebA perfectly symmetrical 3 – Dimensional circular shaped object is a Sphere. The line that connects from the center to the boundary is called radius of the square. You will find a point equidistant from any point on the surface of a sphere. The longest straight line that passes through the center of the sphere is called the diameter of the sphere. WebMar 26, 2015 · The hollow sphere will accelerate slower than the solid one (due to their different moments of inertia). For a solid sphere, the moment of inertia is I = 2 5 m r 2 with mass m and radius r. For a hollow sphere it is I = 2 3 m r 2 The hollow sphere therefore has a greater moment of inertia and will accelerate slower under the same torque:
