10 to 15 minutes
it can stay on forever but the two objects have to be together
When an object is charged by contact, the object getting the charge has the same charge compared with that of the object giving the charge. so if the object giving the charge has a positive charge, so does the object getting the charge
It is called charging by conduction, where one object becomes charged by transferring electrons to or from another object when they are in close contact.
Buoyancy is a contact force that acts on an object submerged in a fluid. It arises from the pressure difference between the top and bottom of an object.
A centripetal force is a contact force that acts on an object moving in a circular path, drawing it toward the center of the circle. It is necessary to keep an object in circular motion and is provided by physical contact with another object or surface.
To properly disinfect an item, it would need to be saturated or immersed in a disinfectant solution for at least 10 minutes. But, 15-20 minutes would be better. If you are trying to sterilize the item, you would need to leave it soaking for at least half an hour.

Because - allowing the residue of disinfectant to air-dry - leaves the active ingredients on the surface longer. Wiping it dry with a cloth defeats the object of keeping the surface bacteria-free.

Non-contact forces are forces exerted on an object by another object which is not in contact with it, a good example being gravitational force.
It is called charging by conduction, where one object becomes charged by transferring electrons to or from another object when they are in close contact.
An object can be electrostatically charged by friction, contact or induction.

The term for the force exerted by an object when it is pushed by another object is "contact force" or "applied force." This force occurs when one object comes into direct contact with another object and pushes or pulls it.
Contact.
