One end of spring is attached to a wall. The other end is attached to a movable block. If you pull the block so as to stretch the spring, which of the following describes the force from the spring? Increase in magnitude constant in magnitude

Solution

According to the problem,

Using the hooks law,

F = - kx where F is the restoring (reaction) force exerted by the spring.

Force is directly proportional to distance x

so, Force increases in magnitude
