URGENT: Using Hooke's law, find the force needed to stretch a spring 2 cm if it has an elastic constant of 3 N/cm

A 6 N
B 3 N
C 2/3 N
D 3/2 N

Respuesta :

Histrionicus

Answer :  A (6 N)

we know that

from Hook's law , F = k.x

                             where, F = force applied on spring 9N)

                                         k = spring constant  (N/cm)

                                         x = distance of spring stretched (cm)

                           Therefore,

                                        F = 2 × 3

                                        F  = 6 N
