Aplatform is free to rotate in the horizontal plane about a frictionless, vertical axle. about this axle the platform has a moment of inertia ip. an object is placed on a platform a distance r from the center of the axle. the mass of the object is m and it is very small in size. the coefficient of friction between the object and the platform is μ. if at t = 0 a torque of constant magnitude τ0 about the axle is applied to the platform when will the object start to slip?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
