The string of a conical pendulum is 54.5 cm long and the mass of the bob is 0.22 kg.

a) Find the angle between the string and the horizontal when the tension in the string is three times the weight of the bob.

b)Under those conditions, what is the period of the pendulum?

• Physics -

sketch the figure.

considering tension, cosTheta=mg/tension

period=2PIsqrt(length/g)
