Answer:
a. k=150N/m, b.W=0.75J,c. W=12J, d.W=9J
Explanation:
a. The Hooke's Law states
, where 
is the force, 
the spring constant and 
the displacement, Knowing the force and the displacement you can find :
b. The work done by a force 
that moves along a displacement 
is:
Then
(Hooke's Law)
Work needed to go from 
to 
c. Work needed to go from to 
d. Work needed to go from 
to
Answer:
-1.0778×10⁻¹⁰ N/C
Explanation:
Applying,
E = kq/r²................ equation 1
Where E = elctric field, q = charge, r = distance, k = coulomb's law
From the question,
Given: q = -3.0×10 C, r = 5.0 m
Constant: k = 8.98×10⁹ Nm²/C²
Substitute these values in equation 1
E = (-3.0×10)(8.98×10⁹)/5²
E = -1.0778×10⁻¹⁰ N/C
Hence the electric field on the x-axis is -1.0778×10⁻¹⁰ N/C
