True or False: If two objects are rubbed together and one becomes positively charged, the other object must have gained an equal magnitude of negative charge.

A person acquires a net negative charge after walking across a rug. When they touch a grounded metal water pipe, what is the resulting direction of electron flow?

If the distance between two small charged spheres is reduced to half of its original value ( $r \rightarrow 0.5r$ ), the magnitude of the electrostatic force between them will change by a factor of:

When a negatively charged rod is brought near a neutral metallic sphere without touching it, the sphere is attracted to the rod. During this process of induction, what is the net charge of the sphere?

A student rubs a piece of polythene with a wool cloth. Based on the triboelectric series provided in the text, which statement correctly describes the electron transfer?

No electrons flow; only protons move

From the pipe to the person

From the ground to the pipe

From the person to the pipe

It becomes negatively charged

It becomes twice as negative as the rod

It becomes positively charged
