Homework Answers
Force of spring is always negative .
From hook's law, F is directly proportional to negative of stretch or compress .
=) F = - Kx
Here K is spring constant or constant of proportionality.
Hence last option is correct.

A 250 g block is moving along the “x” axis and at some point a
force in the positive direction of the axis acts on it.
The graph shows the magnitude of the force versus the position
“x” of the particle. The curve is given by F=a/x^2, with a=9.0 N.m2
. Find the work done on the block by the force as the block moves
from x=1.0 m to x=3.0 m by:
a.) Estimating the work from the graph.
b.)...

A uniform magnetic field points toward the right. The direction for a positive moving charge is 1.0000, where "1" means toward the top of the screen, "2" means into the screen away from you, "3" means toward the bottom of the screen, "4" means out of the screen toward you. What is the direction of the magnetic force on the charge? (use 1,2,3,4 as described in the problem for your response)
