Time period of a simple pendulum is $T$. The angular displacement for amplitude is $\beta$. How much time the bob of pendulum will take to move from equilibrium position $O$ to $A$, making an angle $\alpha$ at the support
$T\,{\sin ^{ - 1}}\left( {\frac{\alpha }{\beta }} \right)$
$T\,{\sin ^{ - 1}}\left( {\frac{\beta }{\alpha }} \right)$
$\frac{T}{2\pi }\,{\sin ^{ - 1}}\left( {\frac{\alpha }{\beta }} \right)$
$\frac{T}{\pi }\,{\sin ^{ - 1}}\left( {\frac{\alpha }{\beta }} \right)$
The ratio of frequencies of two pendulums are $2 : 3$, then their length are in ratio
There is a simple pendulum hanging from the ceiling of a lift. When the lift is stand still, the time period of the pendulum is $T$. If the resultant acceleration becomes $g/4,$ then the new time period of the pendulum is
In the following table relation of graph in column$-I$ and shape of graph in column$-II$ is shown match them appropriately.
column$-I$ | column $-II$ |
$(a)$ ${T^2} \to l$ | $(i)$ Linear |
$(b)$ ${T^2} \to g$ | $(ii)$ Parabolic |
$(c)$ ${T} \to l$ | $(iii)$ Hyperbolic |
Two simple pendulums of lengths $1.44 \,m$ and $1\, m$ start swinging together. After how many vibrations will they again start swinging together
What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of $10\,cm$ ($g = 9.8\, m/s^2$) ..... $m/s$
