Question

An object has charge of $1 C$ and gains $5.0 \times 10^{18}$ electrons. The net charge on the object becomes –

Open in App

Solution

Initial charge = $1 C$
Charge Added = $- (1.6 \times 10^{- 19} \times 5 \times 10^{+ 18})$
= $- 0.8 C$
Final charge = $(1 - 0.8) C$
= $0.2 C$
option (d) is correct answer.

Q. An object becomes charged when the atoms in the object gain or lose.

If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If, however, an object made of substance A is rubbed against an object made of substance C, then A become negatively charged. What will happen if an object made of substance B is rubbed against an object made of substance C?

If an object object contains n₁proton and n₂ectrons,the net charge on the object is??

If an object gains an electron it will become negatively charged and object which looses an electron, it will become positively charged. When they do not come in contact, charge will remain them as it is but they can take or loose charges from the objects.
