A clock $S$ is based on osculation of a spring and a clock $P$ is based on pendulum motion. Both clocks run at the same rate on earth. On a planet having the same density as earth but twice the radius

One-fourth length of a spring of force constant k is cut away. The force constant of the remaining spring will be

A body executes simple harmonic motion under the action of force $F_{1}$ with a time period $\frac{4}{5} s$. If the force is changed to $F_{2}$ it executes simple harmonic motion with time period $\frac{3}{5} s$. If both forces $F_{1}$ and $F_{2}$ act simultaneously in the same direction on the body, its time period will be

The length of second's pendulum is $1\, m$ on earth. If mass and diameter of a planet is doubled than that of earth, then its length becomes:

A simple pendulum has time period $T$. The bob is given negative charge and surface below it is given positive charge. The new time period will be:
