Answer:
Work is equal to the change in kinetic energy.
Explanation:
Since energy cannot be created nor destroyed, and work is a form of energy, the work done by a force acting on an object must be equal to the kinetic energy gained by the object.
This is summarized by the work-energy theorem, which can be written as:
![W=\Delta K = K_f - K_i = \frac{1}{2}mv^2 - \frac{1}{2}mu^2](https://tex.z-dn.net/?f=W%3D%5CDelta%20K%20%3D%20K_f%20-%20K_i%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20-%20%5Cfrac%7B1%7D%7B2%7Dmu%5E2)
where
W is the work done on the object
m is the mass of the object
v is the final speed of the object
u is the initial speed of the object
Answer:
the sheets approach while the object is near
Explanation:
An electroscope is an apparatus that has two metal sheets attached, when these sheets have a charge and distribute evenly between them and the sheets repel.
When I approach an object charged with a counter (negative) charge, part of the charge of the electroscope moves near the charged external object, to neutralize the electric field, so as the charge on one of the plates decreases the electroscope has approached , as the objects are not touched the system remains in this configuration while the object is close. When the object is released, the electric field it creates disappears, so the positive charges repel inside the electroscope and the sheets repel to the initial position.
In short, the sheets approach while the object is near
