Question 2 Given below is a diagram of a conical pendulum which is used by a student and its procedure is shown in the next question. (a) show all the forces acting on the mass(m) if it is moving with a velocity (v) in a circle of radius r. (b) Explain what will happen to angle 0 (the angle between the string and vertical direction) and the linear speed of the mass if the mass of the object increases but the angular speed kept constant by not changing the voltage on the conical pendulum motor. The length of the pendulum also kept constant. (c) Find an expression for the radius in terms of O, L and h whose description is shown in the figure. L h mass (m) Your
