A screwdriver is used to insert a screw into a wall stud. Then, using an electric screwdriver, you drive into the wall. The identical task was done, but the electric screwdriver sped up the process.

An electric screwdriver is a portable tool that allows the user to screw/ unscrew. It's head is outfitted with a bit holder, that can be magnetic or have a quick-release mechanism. A screwdriver should be a must tool in just about any toolbox. It can be used to manually push screws into a range of surfaces such as walls, wood, metal, or porcelain. It is typically used by hand and turn screws with slotted heads.

Therefore, the answer is "Option b".

The statement which is true about using both a screw driver and an electric screw driver to put a screw in a wall stud is: B. the same work was done, but the electric screw driver increased the rate of work.

Work can be defined as a measure of energy transfer that takes place when an object is moved due to the application of a force along a displacement.

Hence, the work done by an object is the multiplication (product) of the perpendicular force acting on the object and the distance it covers.

Mathematically, work done is given by the formula:

$Work\;done = Force \times displacement$

Generally, a screw driver and an electric screw driver can be used to perform the same work of put a screw in a wall stud.

However, an electric screw driver has a motor, which makes the speed (work rate) of putting a screw in the wall faster than a screw driver.

Additionally, a screw driver is a mechanical tool and as such it requires more human effort to put a screw in a wall stud, thereby, decreasing the rate of work.

In conclusion, the same work was done by using both a screw driver and an electric screw driver, but the electric screw driver increased the rate of work.
