Correct Answer - Option 2 : 1 nC
CONCEPT:
-
Electric charge: A physical property of matter due to which the body experiences a force when it is placed in the electric field is known as an Electric charge.
- There are two types of electric charge
- positive
- negative
- When an electron is given to a body or one electron is taken out of the body it has 1 electron charge.
When n electron is given or taken out of a body, the charge it has given by the formula:
q = n × e
where q is the charge on a body, n is no. of electron and e is the charge on one electron.
and e = -1.6 × 10-19 C (charge on one electron)
Formula q = ne (represents quantization of charge)
- It tells us that charge is quantized ( in the form of electrons)
- Every charge has to be an integral multiple of ‘e’.
CALCULATION:
given that charge on the body n = 6.25 × 109
e = 1.6 × 10-19 C
⇒ q = n × e = 6.25 × 109 × (1.6 × 10-19) = = 10-9 C
q = 1 nC
- So the correct answer will option 2.
