First of all you have to find spring constant. For that use readings 5 and 3, and 4 and 2.
Similarly calculate k for the readings 4 and 2. Then using f = - kx find x foe 5 N.
evaluate the value of extension ( x) which elongate under the action of load (w) of 6 N ? [Use your results obtained from rest 1 ]
please help me How i can solve this question because I don't understand it clearly
Experience as follows :
First, we put spring on the board and a paper under spring to measure the distances between each point from the beginning to the end point of extension for each weight
Then we increased laod to ( 0.2 n ) the measurement was between the starting point until end point of extension is 51 mm (( same steps for all load ))
Then we've decrease the weights ( Every time one ) from end ( 0.5 ) to (0,1 ) we got same measurements
then We calculated the average by calculat increases and decreases and divide by 2
For information, there is a Positive relationship between weight and extension
plese help me
