What must be the charge and placement of the third charge
Two charges -Qo and -3Qo, are a distance l apart. These two charges are free to move but do not because there is a third charge nearby. What must be the charge and placement of the third charge for the first two to be in equilibrium. This would be easier if I was given an l amount, but...- shashaeee

Determine the electric field at the centre of the triangle
So with the side triangle: I found the height to be 13.51cm With the bottom dashed triangle... because I need the height to reach the centre, I divided the height of that dashed triangle by 2, so I got: 6.7cm Using the side triangle height, the half height of the bottom dashed triangle and...- shashaeee

Determine the electric field at the centre of the triangle
I'm sorry, I'm really horrible visualizing this, but I think I get what you mean! So, I found the height of the bottom dashed triangle. I divided it in half... Used it with the height of the side triangle I originally found And with Pythagorean Theorom, found the height at the centre then...- shashaeee

Determine the electric field at the centre of the triangle
mhmm, so here is what I did... With the 15.6cm, I used Pythagorean to find the height to be 13.5cm of the side triangle. Then Pythagorean theorom again to find the height of the center, which I calculated to be 11.0cm. Divided that by 2 to get the centre of the triangle. Am I in the right...- shashaeee

What is the voltage across the capacitor plates?
Thanks for the replies! Please correct me if I'm wrong So first, I used the formula Q=CV to look for the charge of the capacitor connected to the 55V battery. Since the battery is removed, the charge Q remains the same right? Now when the dielectric material is inserted to fill the space...- shashaeee

Sketching charging and discharging of the capacitor
Thanks for your reply! So just an idea of putting it together, is it something like this? (Rough sketch) I know it should be curved lines lol- shashaeee

What is the voltage across the capacitor plates?
A 15μF capacitor is connected to a 55V battery and becomes fully charged. The battery is removed and the circuit is left open. A slab of dielectric material is inserted to completely fill the space between the plates. It has a dielectric constant of 4.8. What is the voltage across the capacitor...- shashaeee

Sketching charging and discharging of the capacitor
A simple type of blinking light circuit can be constructed using a neon lamp. The circuit shown here has a 4.0 μF capacitor in parallel with a neon lamp. When the voltage is low in the RC portion of the circuit, the lamp does not conduct electricity. Therefore, it is effectively not there from...- shashaeee

Determine the electric field at the centre of the triangle
Consider an equilateral triangle of side 15.6cm. A charge of +2.0μC is placed at one vertex and charges -4μC each are placed at the two. Determine the electric field at the centre of the triangle. I used Pythagoreom theory to find the height and divided it by 2 but now I'm stuck because I...- shashaeee

What is the magnitude of the charge?
Two 1.0g beads are charged equally and placed 50cm apart. When released, they begin to accelerate at 150m/s2. What is the magnitude of the charge on each bead? The equations I used: F = ma F = kQQ / r2 I was just wondering about the mass. Do I have to use the total mass (2.0g) for both...- shashaeee

Calculate the work needed to move a test charge from point B to D
ohhh, righttt. So, rewriting it .. W = q(VD - VB) VD = VD1 + VD2 VB = VB1 + VB2 where the distance for VD is 25cm and the distance for VB is 35cm- shashaeee
