Question

How negative charge cnduxtor is heavy than positive charge body?

Answer 1

Because for a body to be positively charged, we must remove electrons from the body. So an uncharged body has greater number of electrons as compared to a positively charged body and hence has greater mass.

In the same way, a negatively charged body has greater number of electrons and hence greater mass than an electrically neutral body.

Answer 2

Answer:

Negative charge is heavier than positive charge.

Explanation:

Basically negative charge means protons + neutrons + few more electrons. Whereas positive charge means protons + neutrons - few electrons.
So in both positive charge and negative charge, number of protons and neutrons is same. But in positive charge few less electrons are there, so it becomes lighter, and in negative charge few more electrons are there so it becomes heavier.

Hope this helps.
