A child is playing in a park on a rotating cylinder of radius r is set in rotation at an angular speed of W as shown below. The base of the cylinder is slowly moved away, leasing the child suspended against the wall in a vertical position. What is the minimum coefficient of friction between the child's clothing and wall is needed to prevent it from falling.

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.)
