Three simple pendulums have length of strings `49cms, 48 cms` and `47 cms` with diameters of the bobs `2cms, 4 cm` and `6 cm` respectively. Then their periods are in the ratio

In a simple pendulum experiment, the length of the thread is measured as 102.3 cm and the diameter of the bob as 2.24 cm. What is the maximum possible error in the value of the effective length of the pendulum?

What is the period of a simple pendulum whose length is 50 cm?

The length of the string of a simple pendulum is 102.6 cm and the diameter of the bob is 2.56 cm. What is the effective length of the simple pendulum by using the correct number of significant figures? (Rounding off is not to be considered.)

Two identical simple pendulums oscillate with amplitudes 6 cm and 2 cm respectively. Then ratio of their energies of oscillation are

A solid sphere of diameter 12 cm is melted and three shots are prepared. If the diameters of two shots are 6 cm and 10 cm respectively, what is the surface area (in cm^2 ) of the third shot ?
