Question

let us consider 2 similarly charged particles having force of repulsion 16N with separation between them is 5 m . calculate how many electrons a r missing from each charged particles. class10th

Answer 1

Let us consider q1=q2=q
r=5m; F=16N
F=kq1q2/r²
F=k(ne)(ne)/r² (where q=ne)
F=kn²e²/r²
On putting the values
16=9×10^9n²(1.6×10^-19)²/(5)²
n=4.16
