Question

to make an uncharged object have a negative charge we must

Answer 1

To make an uncharged object have a negative charge we must increase charge on particle and this can be done only by adding electrons to particle.

Answer 2

To make an uncharged object have a negative charge we must add some electrons.

• An uncharged object can be made into a negative or positive charged object by adding or removing some electrons from it.
• Since we need to make the uncharged object into a negatively charged body we need to add some electrons by which the object would gain a negative charge.
• Whenever there is a gain of electrons, the body becomes negatively charged.
