Using hooke's law f spring = k δ x find the force needed to stretch a spring 2 cm if it has elastic constant of 3 n/cm. a. 2/3 n b. 3/2 n c. 6 n d. 3 n

Data:
Hooke represented mathematically his theory with the equation:
 
F = K * x
 
On what:
F (elastic force) = ?
K (elastic constant) = 3 N/cm
x (deformation or elongation of the elastic medium) = 2cm

Solving:





C. 6 N
