Sheena wanted to measure the displacement between two points of her house. She has fixed an iron nail at each point. Which of the following methods can she follow?
a. Tie a thread to the first nail and then tie it to the other nail. Measure the length of the thread between those two points using a ruler.
b. Tie a thread to the first nail and tie the other end of the thread to the second nail so that the thread is taut and measure the length of the thread used using a ruler.
c. Fix one end of the measuring tape to the first nail and stretch it towards the second nail and record the measurement.
If the line between two points is straight, then only it will show displacement.
