The potential energy of a -5 10-6 C charge decreases from 10.2 J to 5.2 J when it is moved from point A to point B. What is the change in electric potential between these two points'?

Electric Potential is given by V=6x-8xy2-8y+6yz-4z2 then the electric force acting on 2 Coulomb point charge placed on the origin will be

If the electric potential at a point in space is considered to be zero, what can be said with certainty about the electric field at the same point?

For each of these calculations you may take that the electric potential is zero infinitely far away from the point charges.

Two point charges Q1=+4.70 n/C and Q2 =-3.20 n/C are seperated by 45.0 cm (a) What is the electric potential at a point midway between the changes? -----V (b) What is the potential energy of the pair of charges? ----J What is the significiant of the algebraic sign of your answer? Positive work must be done to seperate the charges. Negative work must be done to seperate the charges.

1.0 nC + 3.0 cm / \ 3.0 cm 3.0 cm -2.0 nC -2.0 nC Oh no! That triangle is back! Except this time Prof. P was tired of that wonky 1.0 nC positive charge and replaced it with a new exciting and debonair positive 0.2 nC charge (those two boring negative charges and all the distances stayed the same). What is the electric potential energy of this too- exciting for the world arrangement of charges now (in milliJoules)?

The figure shows a cube with a point charge of magnitude 5.98 nC at each corner. 4 of the Charges are positive and the rest are negative. if the cube has sides of length 24.2m and the potential at infinity is zero, what is the potential at the center of the cube?" 出
