Question

A mass of 15 grams stretches a spring

Answer 1

Answer:

36 grams mass will stretch the spring  12 centimeters.

Step-by-step explanation:

Here, Distance of the spring ∝ The Mass attached

or D = k M ( for some arbitrary constant k )

Now, for  m = 15 g, D = 5 centimeters

So, here  5 = k(15)

or, $k = \frac{5}{15} = \frac{1}{3}$

⇒ For  D=  12 cm , D = k M

⇒   $12 = \frac{1}{3} \times M\\M = 12 \times 3 = 36$

or, M = 36 grams

Hence, 36 grams mass will stretch the spring  12 centimeters.
