Some metals having unpaired electrons contain a strong magnetic response, i.e, they can be magnetized by an external magnetic field.
The force required to pull one of the microscope sliding at a constant speed of 0.28 m/s relative to the other is zero.

Force required to pull one end at a constant speed</h3>
The force required to pull one of the microscope sliding at a constant speed of 0.28 m/s relative to the other is determined by applying Newton's second law of motion as shown below;
F = ma
where;
- m is mass
- a is acceleration
At a constant speed, the acceleration of the object will be zero.
F = m x 0
F = 0
Thus, the force required to pull one of the microscope sliding at a constant speed of 0.28 m/s relative to the other is zero.
