Question

what is the force constant of a spring which is stretched to metre millimetre by a force of 4 newton​

Answer 1

Answer:

The spring force expression analytically is given as

Spring force magnitude = (Force constant)*(displacement from nature length)

So, According to the given date in the question

4 N = (Spring constant)*(10^-3 metre)

So,

Spring constant = 4*10^3 Newton/Metre

or,

k= 4000 N/m

Hope this helps you !

Answer 2

Formula used :-

F= -kx

Given :-

x= 3x10^(-3) m

F= 4N

Step by step Explaination :-

Since,

F= -kx

and we have been given the F and x,

So, here we see

→ F= -kx

→ 4N= -k(3x10^(-3))

→4/3x10³=(-k)

→-4/3x10³=k

So, force constant is -4/3x10³N/m
