Question

1) How much force is needed to pull a spring with a spring constant of 20 N/m a distance of 25 cm?

Answer 1

Answer:

5 newtons

Explanation:

Given :

• Value of the spring constant of the spring = 20 N/M

• Change in distance = delta X = 25 cm = 0.25

To find :

• Force required to pull the spring with a spring constant of 20 N/M and distance of 25 cm

Force required to diaplace a spring = k × delta X

Here :

K = spring constant = 20 N/M

Delta X = 0.25

Force required = 20×0.25

Force required = 5 Newtons

The force required to diaplace the spring is 5 Newtons

Answer 2

Given :-

• Value of spring constant (k) = 20N/m

• compression (X) =25 cm=25/100=0.25m

To Find :-

• Force (F) needed to pull spring.

Solution :-

Spring constant (k) = 20N/m

Compression (x) =0.25m

we know that ,

Spring constant K = F/X

☛ 20= F/0.25

☛ F =20× 0.25

☛ F= 5 N

∴The needed to pull spring is 5 N.
