The equipotential curves due to a positive and a negative charge of the same magnitude separated by a distance of 1 m are circles. True or False.
The positive and negative charge situated 1m apart so they makes a electric dipole p
So the potential due to this dipole is
V = k*p*cos(x) /r^2
So the curve of potential v is not a circle it is

Equipotential surfaces A positive point charge is surrounded by an equipotential surface A, which has a radius of rA. A positive test charge moves from surface A to another equipotential surface B, which has a radius rB. In the process, the electric force does negative work (a) Does the electric force acting on the test charge have the same or opposite direction as the displacement of the test charge? O The electric force has the same direction as the displacement...

Problem 3 A negative point charge with magnitude |gol and a positive point charge with magnitude |2gol are a distance a apart. Where should a third point charge be placed so that the electric force on that third charge is zero? Does your answer depend on the sign of the third point charge? Why or why not?
A positive charge is moved from one point to another point along an equipotential surface. The work required to move the charge depends on the magnitude of the potential. depends on the sign of the potential. is negative. is zero. is positive.
