20. If a boy observed that a pen rubbed on his dry hair attracted a nearby neutral piece of paper, the cause of the attraction is: Electrostatic forces (D)
21. If the distance from a point in the electric field is decreased by half, the electric potential at that point will: Increase four times (C)
22. The potential difference between the plates of a parallel plate capacitor with a distance of 1cm between plates and electric field strength of 10J/c is: 0.13V/c (B)
Explanation:
The term "Friction charges" refers to the process of charging an object by rubbing it against another material. When two materials are rubbed together, electrons can be transferred from one material to the other, creating a static electric charge. The resulting charge on the object is referred to as "friction charges."
In terms of Loss electrons, it refers to a situation in which an object loses electrons and becomes positively charged. This can occur when electrons are transferred from the object to another material through processes such as friction charging or electrical discharge. When an object loses electrons, it has a surplus of positively charged particles and is said to have a positive charge.
