How do you find the zero field location?

Just find the expression of E at any location in the line of the two charges and solve E = 0 for x. Your book finds the distance of the point from q2.

At which point or points is the electric field zero in?

1. The electric field is zero at two points along the x axis; one such point is to the right of the -2q charge and the other is to the left of the +4q charge.

Where is the zero field location for two equal and opposite charges?

There is no zero-field point for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.

Is the electric field zero between two opposite charges?

The electric field will not be zero between two opposite charges. For opposite charges, the point of zero electric fields will lie outside the system along the line joining the two charges.

How is electric field zero?

To find where the electric field is 0, we take the electric field for each point charge and set them equal to each other, because that’s when they’ll cancel each other out. The ‘s can cancel out. Therefore, the electric field is 0 at .

Where is the electric field the greatest between two opposite charges?

The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.

Where is electric field maximum two opposite charges?

It can’t be between the two opposite charges because there the field vectors from both charges point toward the negative charge. It has to be on one side or the other of both of them, where the vectors point in opposite directions.

Can the electric field intensity be zero at the Centre of I 2 equal charges II 2 equal and opposite charges explain why?

The electric field between two opposite charges are in the same direction and add, so the sum is never zero. The electric field strength E is nowhere zero in such a case.
