Question #35e62

Answer 1

The most accurate answer is `1.8 MV`!

Explanation:

The actual equation for Potential is, `V=(1/4πε)(Q/r)`
Where, `ε=8.854×10^-12` `C^2`/`Nm^2`

`π=3.14159`

`Q=20×10^-6 C`
=`20μ C`

`r=20/2 cm`
=`10` x `10^-2 m`
= `0.1m`

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 MV`

I hope that helped!
