Homework Answers
Correct options are : 1 and 2 because only the lengths differ.
Reason : To observe the effect of length on time period, it is better to keep all other parameters same, so that we can vary the length and record the time taken to complete one oscillation. Since the mass attached to string 3 differs from that attached to strings 1 and 2, we should not choose string 3 as a part of our experiment.

A rigid, uniform, horizontal bar of mass m1 and length L is
supported by two identical massless strings. (Figure 1) Both
strings are vertical. String A is attached at a distance d<L/2
from the left end of the bar and is connected to the ceiling;

the floor. A small block of mass m2 is supported against gravity by
the bar at a distance x from...

Consider the two strings "doggie dish" and "Drip coffee". What letters do they have in common? That is, what is the letter intersection count for the pair of strings? Let's look at 'd' first. The first string has 2 d's (d's occurrence count is 2), while the second has just 1 d (capitalization doesn't count) - so the intersection for the strings for d is 1. What about g? There the occurrence counts are 2 and 0, so the intersection...
