Question

calculate the potential at a point 10 cm away from a point charge +1C in air​

Answer 1

Answer:

Potential 'V' due to a point charge 'q' is given as

$V = \frac{kQ}{r}$

taken referance as V(∞) = 0

k = 9 x 10⁹ Nm²/C²

Q = 1 C

r = 0.1m

V = 9 x 10⁹ x 1 / 0.1 = 9 x 10¹⁰ V

V = 9 x 10¹⁰ V

Answer 2

${\fbox{\fbox{\fbox{\large\sf\pink{AnsWeR}}}}}$

❥Potential 'V' due to a point charge 'q' is given as

$\sf{V =>\frac{kQ}{r}}$

$Taken \:referance\; as\:{\sf{V(∞) => 0}}$

$\sf{k => 9 x 10⁹ Nm²/C²}$

$\sf{Q =>∆ 1 C}$

$\sf{r =>0.1m}$

$\sf{V => \frac{9 x 10⁹ x 1 }{ 0.1} = >9 x 10¹⁰ V}$

$\sf{V => 9 x 10¹⁰ V}$
