I'm reading my physics textbook right now and it states that when you add a dielectric between two capacitors you are: 1. Increasing the potential difference between the two plates. 2. Increasing capacitance by decreasing V (Q/V=C) Isn't this contradictory? I thought that V in the equation...

Ok, I finally understand the problem now. Thank you so much for your help! I appreciate it =)

It would have 1/8 less volume...so then Q/8

Would it have half the charge it originally had? Q/2?

Oh ok, so then the E field for the first sphere would be: \frac{1}{4_{0}\epsilon\pi}\frac{Q}{\frac{1}{2}R^{2}} And then since both fields of the spheres are pointing the same direction I will just add the E fields of the first sphere with the second sphere?

Homework Statement The left-hand sphere has a positive charge Q and the right-hand sphere has a negative charge -Q . Charge is distibuted uniformly over each of two spherical volumes with radius R. One sphere of charge is centered at the origin and the other at x=2R . Find the magnitude of...

Homework Statement Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 400 km above the Earth's surface; at the high point, or apogee, it is 4000 km above the Earth's surface. 1. What is the period of the spacecraft 's...

I have kind of a stupid question to ask, but its just something I really don't understand. So in pictures (like the one below) where an object is sitting on an inclined plane, why is it that the angle between the force of gravity and the incline plane is the same as the angle of the incline...
