Answer 1

1. Question⇒   A spherical hollow cavity is made in a lead sphere of radius r

Explanation:

• A spherical hollow is inside a lead sphere of radius R=3.4 m; the surface of the hollow passes through the center of the sphere and 'touches' the right side of the sphere. The mass of the sphere before hollowing was M=400 kg, and the diameter of the spherical hollow is equal to the radius of the lead sphere.
