Answer
Force is necessary to stretch a spring 0.5 m when the spring constant is 190 N/m is 95 N .
Explanation:
By using Hookes law .
The force required to extend a spring is directly proportional to the distance you stretch it .
Thus
F = kx
Where F is force , k is spring constant and x is the extension of spring .
As given
A spring is stretch to 0.5 m .
The spring constant is 190 N/m .
x = 0.5 m
k = 190 N /m
Putting all the values in the formula
F = 190 × 0.5
= 95 N
Therefore the force is necessary to stretch a spring 0.5 m when the spring constant is 190 N/m is 95 N .
