According to Coulomb-apos-s Law-xA0-E-kQr2where E is electric field- q is charge at a distance r and k is a constant- Therefore-xA0-E-x221D-1r2

The intensity of electric field E due to charge Q at distance r.E∝rE∝1r3E∝1rE∝1r2

According to Coulomb's Law: E=kQr2where E is electric field, q is charge at a distance r and k is a constant. Therefore, E∝1r2

The intensity of electric field E due to charge Q at distance r.
$E \propto r$
$E \propto \frac{1}{r^{3}}$
$E \propto \frac{1}{r}$
$E \propto \frac{1}{r^{2}}$

According to Coulomb's Law:
$E = k \frac{Q}{r^{2}}$
where E is electric field, q is charge at a distance r and k is a constant. Therefore,
$E \propto \frac{1}{r^{2}}$
