Two point charges+ q and-q are placed at distanced apart. What are the points at which the resultant field is parallel to the line joining the two charges ?

Fig. shows some of the electric field lines due to three point charges arranged along the vertical axis. All three charges have the same magnitude. (a) What are the signs of each of the three charges? Explain your reasoning. (b) At what points(s) is hte magnitude of hte electric field the smallest? Explain your reasoning. Explain how the fields produed by each individual point charge combine to give a small net field at this point or points. (c ) Two point charges q and -q are placed at a distance d apart. What are the points at which the resultant electric field is parallel to the line joining the two charge? .

At what points, dipole field intensity is parallel to the line joining the charges ?

Two point charges Q and - Q //4 are separated by a distance X . Then .

Two electric +q and +4q are placed at a distance 6a apart on a horizontal plane. Find the position of the point on the line joining the two charges where the electric field is zero.

Two point charges +4q and +q are placed 30cm apart. At what point on the line joining them is the electric field zero

Two point charges of +10muC and +20muC are placed in free space 2 cm apart. Find the electric potential at the middle point of the line joining the two charges.

Two points charges q and -2q are placed some distance d apart. If the electric field at the location of q is E, that at the location of -2q is

Two point charges q and -2q are kept 'd' distance apart. Find the location of the point relative to charge q at which potential due to the system of charges is zero.
