Two spheres are made of same metal had and have same mass. One is solid and the other is hollow. When heated to the same temperature, percentage increase in diameter will be

Two sphere are of same mass and same external radius, one is solid and the other is hollow. Which one of them has larger moment of inertia about its diameter?

Consider two conducting spheres of radii of R_1 and R_2 with R_1 > R_2 . If the two are at the same potential the larger sphere has more charge than the smaller spheres. State whether the charge density of the smaller sphere is more or less than that of the larger one.

A lighter body and a heavier body have same K.E. Which one has greater momentum?

Two wires of equal lengths, one of copper and the other of manganin, have the same resistance. Which wire is thicker?

Two isolated metallic solid spheres of radii R and 2R are charged, such that both of these have same charge density. The spheres are located far away from each other and connected by a thin conducting wire. Find the new charge density on the bigger sphere.
