Consider a conical pendulum with a bob of mass m = 81.0 kg on a string of length L = 10.0 m that makes an angle of ? = 6.00° with the vertical. (Consider + to be towards the center of the circular path and + to be upward.)

(a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum.

? N + ? N

(b) Determine the radial acceleration of the bob.
