Question

A typical charge produced by rubbing is 1nc. Roughly no. of elementary charges (e) doesinvolve in n. If n is given as xx 10' Find x​

Answer 1

Hey Dear,

● Answer -

x = 6.25

◆ Explaination -

# Given -

Q = 1 nC = 10^-9 C

e = 1.6×10^-19 C

N = x×10^y

# Solution -

Let N be number of electrons involved in formation of static electricity.

Total charge produced is given by -

Q = N × e

10^-9 = N × 1.6×10^-19

N = 6.25×10^9 electrons

Comparing this to N = x×10^y,

x = 6.25

x = 6.25y = 9

Therefore, value of x must be 6.25 .

Thanks for asking..
