Question

A spring with a spring constant of 400 N/m has a mass hung on it so that it stretches 8 cm. Find weight attached to it.

Answer 1

Answer:

bro I don't no search in doubtnet app

Answer 2

Answer:

$given : k = 400n|m \\ displacement(x) = 0.08m \\ g = 9.8\\ \\ to \: find: mass \\ solution:( force)f =kx \\ f =( 400 \frac{n}{m} ) \times( 0.08m) \\ so \: f \: and \: weight = 32n \\ mass = \frac{force}{g} \\ mass = \frac{32}{9.8} \\ mass = 3g$

and note that weight is 32 newton
