Question

1. If a 3kg bowling ball were suspended from a 5m piece of fishing line, what would be the period of oscillation?

4.49 seconds. (already answered bit providing as context for next question)

2. Now, if instead of fishing line, that same 3kg bowling ball were suspended from a 5m cable with a mass fo 2kg, would the period be different? Why?

a. No, the period would not change because mass doesn't matter for a simple pendulum.

b. Yes, the period would change because, even though it is still a simple pendulum, the mass has changed.

c. No, the period would not change because the length is the same.

d. Yes, the period would be different because this is no longer a simple pendulum.

Answer 1

In this question we have to find the new value of time period if mass cable is replaced with a cable of mass 2kg.
