Question

The spring constant of two springs is 3N/cm and 5N/cm. Explain why it is more difficult to stretch the second spring than the first

Answer 1

The second spring will be more difficult to stretch than the first because the force required will be more

Explanation:

Given

Spring constants of the springs = 2 N/cm and 5 N/cm

We know that if a spring is stretched or compressed with a distance x and if the spring constant is k

Then, the force required

$F=kx$

Now, if both the springs are stretched or compressed by same distance x then we can see that

$F\propto k$

i.e. the spring which has greater spring constant will require greater force to stretch or compress

Hence we can say that the second spring (k = 5 N/cm) will be more difficult to stretch than the first spring.

Hope this answer is helpful.
