Question

The spring in the figure stretches from 10 cm to 22 cm when a force of 4 N is applied. Calculate:
its force constant k

Answer 1

• spring force = Kx = 4n
• here x = 12 m
• so k = 4 / 12 = 33.33 ans

Answer 2

Answer:

we know the formula that F=-k(Delta x)

Explanation:

F=4N

Delta x =x2-x1=12

there fore 4=-k(12)

k= 4÷12

k=1/3
