Question

You need to make a spring scale to measure the mass of objects hung from it. You want each 2.1 cm length along the scale to correspond to a mass difference of 0.10 kg. What should be the value of the spring constant?

Answer 1

Answer:

k = 46.67 N/m

Explanation:

given,

mass, m = 0.10 Kg

Length, x = 2.1 cm = 0.021 m

spring constant, k = ?

we know,

spring force

F = k x

and also

F = m g

computing both the equation

k x = m g

$k = \dfrac{mg}{x}$

$k = \dfrac{0.1\times 9.8}{0.021}$

k = 46.67 N/m

Spring constant for the spring is equal to k = 46.67 N/m

Answer 2

Answer:

46.67 N/m

Explanation:

mass, m = 0.1 kg

distance, y = 2.1 cm = 0.021 m

Let K be the spring constant.

F = mg = Ky

0.1 x 9.8 = K x 0.021

K = 46.67 N/m

Thus, the spring constant of the spring is 46.67 N/m.
