2 electrical charges in an field will point tot eh opposite direction and the net force on dipole is 0.
torque=2Fsin(theta)=2qEsin(theta)=PEsin(theta)=PxE(vectors cross product)
Then using integral find change in potential energy.
U2-U1=PE(cos(theta1)=cos(theta2))
draw the electrical field lines on the board.
Then we use Vpython to draw the electrical field lines.
Flux=Acos(theta)kq/r^2=EAcos(theta)
m^2 N/C
open space:
flux=E.A(dot product)
closed space
flux=integral of E.dA(vectors)
Below is a question, finding eh flux within the rectangular box. what will be the flux total? left side and right side cancel out, The answer is 0
