R P Goyal and S P Tripathi Solutions for Chapter: Measurements and Experimentation, Exercise 3: EXERCISE–1 (C)

The time period of a pendulum clock is :

The length of the seconds' pendulum is nearly:

A seconds' pendulum is taken to a place where acceleration due to gravity falls to one-fourth. How is the time period of the pendulum affected? Give reason. What will be its new time period?

Find the length of a seconds' pendulum at a place where $g=10 \mathrm{m} {\mathrm{s}}^{-2}$. (Take $\mathrm{\pi }=3.14$) 

Compare the time periods of two pendulums of length $1 \mathrm{m}$ and $9 \mathrm{m}$.

The time periods of two simple pendulums at a place are in the ratio $2:1$. What will be their ratio of lengths?

It takes $0.2 \mathrm{s}$ for a pendulum bob to move from mean position to one end. What is the time period of the pendulum?

How much time does the bob of the seconds' pendulum take to move from one extreme of its oscillation to the other extreme?
