Yeah that's the problem I'm running into - without the angle, it seems impossible. However, is there a solution possible using the sagitta.

Homework Statement Given a circle with a set diameter, how does one calculate the area of the segment below? Homework Equations The only information available is the diameter (in this particular example it is 14"), You may not use angles. Only the chord length. Thank you for your reply. Miguel

What should the equation be then for all 4 charges? K(Q1 + Q2 + Q3 + Q4) / 2cos(45)? Also, what would Ri be then?

Homework Statement Identical point charges (+50 μC) are placed at the corners of a square with sides of 2.0-m length. How much external energy is required to bring a fifth identical charge from infinity to the geometric center of the square? Homework Equations Electric Potential for Multiple...

Thanks again Qwerty. I must have missed out on that equation when I was copying my notes.

Ahhh. Point VB has higher potential energy, therefore, in the equation VB - VA, it is positive. Thank you for your response. I also have another question. A particle (charge = +2.0 mC) moving in a region where only electric forces act on it has a kinetic energy of 5.0 J at point A. The...

Homework Statement A charged particle (q = -8.0 mC), which moves in a region where the only force acting on the particle is an electric force, is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electric potential difference...
