Consider a conical pendulum with a 84.0 kilogram bob on a 10.0 meter wire making an angle of θ = 3.00 degree with the vertical. (Consider + to be towards the center of the circular path.)
(a) Compute the vertical and horizontal components of the force exerted by the wire on the pendulum.
(b) Determine what is the radial acceleration of the bob?
