(B) 6
(C) 2
(D) 1
Answers
Given:
Static charge of a particle = -6.4×10⁻¹⁹ C
To find :
The number of electrons present in the particle
Calculation:
The charge of a particle having ‘n’ electrons is given by the formula
q = ne
By substituting the values given in the formula
=> q=ne
-6.4×10⁻¹⁹= n×(-1.6×10⁻¹⁹)
n = (-6.4×10⁻¹⁹) / (-1.6×10⁻¹⁹)
n = 6.4 / 1.6
n = 4
Final answer :
The number of electrons present in the particle is 4
