How many electrons must be transferred to a body to produce a charge of NC?

How many electrons must be transferred to a body to produce a charge of NC?

charge to be produced =125 nc or 125*10^-9 c. to find: Number of electrons required to produce a charge of 125 nc. so, 78 x 10^10 electrons must be transferred to a body to produce a charge of 125nc.

How many electrons must be removed from a body to give it a charge of 1mc?

6×1018 electrons.

How many electrons would have to be removed from a coin to leave it with a charge of +2.9 10 6 C?

Answer Expert Verified 625 billion electrons should be removed from [neutral] coin.

How many electrons would be required to have a total charge of 1.00 C on a sphere?

Answer. Electron has charge of 1.6 × 10−19 C so 6.65 * 1018 electrons constitute a coulomb of charge. e =1.6 × 10−19 C. Total charge required 1 Coulomb.

What is a Coulomb equal to?

One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 10-19 C. Conversely, the charge of an electron is -1.6 x 10-19 C.

What does positively charged mean?

Atoms, which are the basic unit of matter, have a dense nucleus made up of positively charged protons and neutral neutrons. Surrounding the nucleus are negatively charged electrons. If an object has a positive charge, that means it has lost some electrons and now has more protons than electrons.

Do positively charged objects attract?

These two types of electrical charges – positive and negative – are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Objects with like charge repel each other.

Why does a perspex rod become positively charged when rubbed with a dry cloth?

opposite charges attract each other Similarly, when a piece of Perspex is rubbed with a cloth it becomes positively charged. Electrons have been rubbed from the Perspex onto the cloth. Again, the rod and the cloth have opposite charges and will attract each other.
