A force of constant magnitude `F_(0)` is applied in the tangential direction as shown in the figure. Assume that the bob is at its lowest point initially. A. Speed of bob at `theta=60^(@) " is "sqrt((2L)/(m)[(F0pi)/(3)+(mg)/(2)])`B. Speed of bob at `theta=60^(@) " is "sqrt((2L)/(m)[(F0pi)/(3)-(mg)/(2)])`C. Tension in thread at `theta=60^(@) " is "[(2F0pi)/(3)-(mg)/(2)]`D. Tension in thread at `theta=60^(@) " is "[(2F0pi)/(3)+(mg)/(2)]` |
