Is it possible for any arrangement of two point charges to find two points neither at Infinity at which E 0 if so under what conditions?

point not between the charges but on the line joining them, what are the necessary conditions and where is the point located(b) Is it possible, for any arrangement of two points charges, to find two points (neither at infinity) at which E=0 if so under what conditions? That point is called neutral zone.

Which of the two charges Q1 and Q2 is greater in magnitude?

From the graph, it can be seen that net potential due to the two charges is positive everywhere in the region left of charge Q1. Therefore, the magnitude of potential due to charge Q1 is greater than that due to Q2. Therefore, the absolute value of charge Q1 is greater than that of Q2.

How do you find the null point between two charges?

In the region between the 2 charges, the electric field lines will originate at the + charge and terminate at the – charge. Remember that the electric field lines point in the direction of the force on a positive test charge. Therefore the null point of the electric field must lie outside the charges.

How do you find electric field with distance and charge?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

What is the magnitude of the charge?

The magnitude of the electric field is simply defined as the force per charge on the test charge. The standard metric units on electric field strength arise from its definition. Since electric field is defined as a force per charge, its units would be force units divided by charge units.

What is the nature of electrostatic force between two point charges q1 and q2 if q1 q2 0?

The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative). The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative).

What is the nature of force between two charges q1 and q2 if q1 q2 is greater than zero?

If q1q2 > 0, then both q1 and q2 are likely charged (either both positively charged or negatively charged) and there will be electrostatic force of repulsion between them.

What are two point electric charges of unknown magnitude and sign?

Two point electric charges of unknown magnitude and sign are placed at some distance ‘d’ apart. The electric field intensity is zero at a point, not between the charges but on the line joining them.Write two essential conditions for this to happen. >> Two point electric charges

What are the two essential conditions for two point electric charge?

Two essential Conditions are : The two point electric charge must have opposite signs. ( this is because if the two charges would have the same sign, the null point would lie b/w the two charges. The null point is closer to the charge of smaller magnitude. Write Biot-Savart’s law in vector form.

How can the electric field be zero between two charges?

For the electric field to be zero between the two charges, the electric field must cancel out and point in opposite directions. If two different charges are present, the electric field travels from the positive charge to the negative charge. A negative charge will tend to accelerate in the opposite direction of the electric field.

Can two charges of the same charge have the same sign?

Both the charges can not be of same sign. The observation point (where electric field intensity is zero) has to be closer to the smaller charge than to the bigger charge. Ans.
