Answer 1

Answer:

F = KX

F= 20 × 0.25

5N

Explanation:

5N is your answer

Answer 2

Given :-

Spring constant = 20 N/m

Compression = 25 cm

To Find :-

Force required to pull the spring.

Analysis :-

Here we are given with the spring constant and compression.

In order to find the force applied substitute the given values in the question using the Hooke's law and find the force accordingly.

Solution :-

We know that,

• k = Spring constant
• f = Force
• x = Compression

Using the formula,

$\underline{\boxed{\sf Hooke's \ law=\dfrac{Force}{Compression} }}$

Given that,

Spring constant (k) = 20 N/m

Compression (x) = 25 cm = 0.25 m

Substituting their values,

⇒ 20 = f/0.25

⇒ f = k × x

⇒ f = 20 × 0.25

⇒ f = 5 N

Therefore, the force required to pull the spring is 5 N.
