A positive charge of q₁ is located 5.54 m to the left of a negative charge q2. The charges have different magnitudes. On the line through the charges, the net electric field is zero at a spot 1.52 m to the right of the negative charge. On this line there are also two spots where the potential is zero. (a) How far to the left of the negative charge is one spot? (b) How far to the right of the negative charge is the other? (a) Number i (b) Number i Units Units

The electric potential V in a region of space is given by V(x, y, z) = A(x² – 3y² + z?) where A = 4.00x103 J/(C-m²). a) What is the electric field at the point (1.00 m, 1.00 m, 1.00 m)? b) If an 8.854 x 10-12 kg test charge of +1.50 µC were placed at the point (0, 0, 1.00 m) and released from rest, will it move toward the origin or away from the origin? Explain. c) After starting from rest at the point (0, 0, 1.00 m), what will be the speed of the test charge after it has traveled 1.00 m along the z-axis?

4 charges, each 2 nC worth of charge, are arranged on the 4 corners of a square. The side length of the square is 1 meter. What is the electric potential in the center?

A charge -78 pC is placed at the origin and a charge 32 pC is placed at a distance of 5 cm from the origin on the x-axis. Find the location from the origin where the net electric potential is zero. Distance from the origin =? What is the potential energy of a charge 58 μμC placed at a distance of 0 cm from the origin on the x-axis

A charge q is placed at the origin of the x-axis and another charge of charge -3.50 nC is placed 5.80 cm to its right. It is found that the electric potential due to the two charges is zero at x = 1.93 cm. What is q? The charge is:
