Charged particles #1 and #2 are 0.4 cm apart in air and exert a 100 Nt on force each other. If the 2 charges (at the same distance) exert a 25 Nt for on each other in substance "blox", then "blox" has a dielectric constant of:

• Phys -

E=q/episilion

episilion=4, E reduced to 1/4. Think about it, what does a dielectric do?

• Phys -

it's an electrical insulator...so I would set my equation up as

1/4 = q/4 ? Is this correct? But then my answer equals 1, which isn't an answer choice. I'm sorry, but I'm just not getting this...

• Phys -

What equation?

In a parallel field, E=q/episilion.

If E goes down by 4, episiolon has to increase by 4. The answer is 4.
