Consider a pair of identical pendulums, which oscillate with equal amplitude independently such that when one pendulum is at its extreme position making an angle of $2^o$ to the right with the vertical, the other pendulum makes an angle of $1^o$ to the left of the vertical. What is the phase difference between the pendulums ?
The time period of a simple pendulum of length $L$ as measured in an elevator descending with acceleration $\frac{g}{3}$ is
The length of simple pendulum is increased by $44\%$. The percentage increase in its time period will be ..... $\%$
When will the motion of a simple pendulum be simple harmonic ?
The length of a simple pendulum is increased by $1\%$. Its time period will
