In a conical pendulum, a string of length 120 cm is fixed at a rigid support and carries a bob of mass 150 g at its free end. If the bob is revolved in a horizontal circle of radius 0.2m around a vertical axis, calculate the tension in the string. [g = 9.8 m/s2 ] |

Answer» Data : L = 120 cm = 1.2 m, m = 150 g = 0.15 kg, r = 0.2 m, g = 9.8 m/s2 sin \(\theta\) = \(\frac{r}L\) = \(\frac{0.2}{1.2}\) = \(\frac{1}6\) |
