Instead of moving back and forth, a conical pendulum moves in a circle at a constant speed as its string traces out a cone (Fig. P6.68). One such pendulum is constructed with a string of length L = 12.0 cm and bob of mass 0.210 kg. The string makes an angle θ = 7.00° with the vertical, a. What is the radial acceleration of the bob? b. What are the horizontal and vertical components of the tension force exerted by the string on the bob?
