# Question 35e62

Aug 7, 2015

The most accurate answer is $1.8 M V$!

#### Explanation:

The actual equation for Potential is, V=(1/4πε)(Q/r)
Where, ε=8.854×10^-12 ${C}^{2}$/$N {m}^{2}$

π=3.14159

Q=20×10^-6 C
=20μ C

$r = \frac{20}{2} c m$
=$10$ x ${10}^{-} 2 m$
= $0.1 m$

If you know at least how to operate a calculator, the calculator will give you 1797550.006 .
So the potential is 1.79 ×10^6 V
1.8 ×10^6 V#
= $1.8 M V$

I hope that helped!
