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?

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
