Answer 2

Given ,

Charge (q) = 1 μC or 1 × (10)^6 C

Distance (r) = 10 cm

We know that , the electric potential due to point charge at a distance r is given by

$\large \sf \fbox{V = k \frac{q}{r} }$

Where ,

k = coulombs constant = 9 × (10)^9 Nm²/c²

Thus ,

$\sf \mapsto V = \frac{9 \times {(10)}^{9} \times {(10)}^{6} }{10} \\ \\ \sf \mapsto V = 9 \times {(10)}^{14} \: \: volt$

$\sf \therefore \underline{The \: electric \: potential \: is \: 9 × {(10)}^{14} \: \: volt}$
