Question

O forta de 30N, actionand in lungul unui resort, ii produce acestuia o deformare de 6 cm. Ce valoare are o alta forta, care, actionand pe aceeasidirectie, produce aceluiasi resort o deformare de 10cm?

Answer 1

$F_1=kx_1\ \ \ \ \Rightarrow \ \ \ \ k=\dfrac{F_1}{x_1}\\ \\ \\ F_2=kx_2=\dfrac{F_1}{x_1}x_2=\dfrac{30}{6}\cdot 10=50\ N.$
