Consider a solid cone with uniform density \rho, height h, and circular base with radius r (mass hr ). let the vertex of the cone be the origin of the body frame. by symmetry, choose basis vectors \mathbf{e}_{i} for the body frame such that the inertia tensor i_{ij} is diagonal.
(a) will this rigid body with this body origin be an asymmetric top, a symmetric top, or a spherical top? calculate the inertia tensor in this basis.
(b) how will the inertia tensor change if we change the body origin to the center of mass while the basis vectors remain fixed? hint: steiner’s parallel axis theorem might with this part of the problem.

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
