Avertical spring has a spring constant of 100 newtons per meter. when an object is attached to the bottom of the spring, the spring changes from its unstretched length of 0.50 meters to a length of 0.65 meters. the magnitude of the weight of the attached object is
a. 1.1n
b. 15n
c. 50n
d. 65n

option B

Explanation:

given,

spring constant = k = 100 N/m

distance of unstretched length = 0.5 m

distance after stretched length =  0.65 m

magnitude of weight = ?

We know,

W  = K x

x is the displacement

x = 0.65 - 0.5 = 0.15 m

W = K x

W  = 100 x 0.15

W  = 15 N

Hence, the correct answer is option B

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
