Answer to Question #286836 in Atomic and Nuclear Physics for Mike

Question

Description:Two equal charges are separated 75cm apart in free air. Calculate the quantity of either charge if the force between them is 0.17N. What will be the quantity if the charges are situated in an insulating medium of dielectric constant= 10?

Answer 1

a.

$q=r\sqrt{\frac{F}{k}}=3.26~\mu C,$

b.

$q'=r\sqrt{\frac{\varepsilon F}k}=10.3~\mu C.$
