Question

5) tf the clecical force of repulsan vetwn れN1.Came, amount 6f charges is 10 N, andl the are 30000 m cpart. What s the magniude of each Charac ?

Answer 1

Given $F=10N$

$d=30000m$

and $q_{1}=q_{2}$

$F=kq_{1}q_{2}/d^{2}$

$10N=9*10^{9}q_{1}q_{2}/(30000m)^{2}$

$10=9*10^{9}q_{1}q_{2}/30000^{2}$

$10*30000^{2}/(9*10^{9})=q_{1}q_{2}$

$(9*10^{9})/(9*10^{9})=q_{1}^{2}$

$1=q_{1}^{2}$

ANSWER: $q_{1}=q_{2}=1C$
