In summary, the formula for calculating the distance between two charges is given by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The distance between two charges has an inverse relationship with the strength of the force between them, meaning that as the distance increases, the force decreases. The distance between two charges can never be zero as this would result in an infinite force, which is not physically possible.

1.Two point charges, Q1 = -22 mμ C and Q2 = 51mμ C , are separated by a distance of 12 cm. The electric field at the point P is zero. How far is Q1 from P?...Sorry if my equations arent coming out right on the screen this is the first time I've posted on the forum, if you look at the thumbnail I've posted its the way I am doing the problem

2 k Q2
(x+d)^2
3. i keep getting an answer of 29 using the formula in the thumbnail

In your working you have Q1 = Q2/2, which is not the case.
 

FAQ: How Far is Charge Q1 from Point P Where the Electric Field is Zero?

What is the formula for calculating the distance between two charges?

The formula for calculating the distance between two charges is given by the Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, it can be written as F = k * (q1 * q2)/d^2, where F is the force, k is the Coulomb's constant, q1 and q2 are the charges, and d is the distance between them.

How do the distance between two charges affect the strength of the force between them?

The distance between two charges has an inverse relationship with the strength of the force between them. This means that as the distance between the charges increases, the force decreases, and vice versa. This relationship is represented by the inverse square law in Coulomb's Law.

Can the distance between two charges ever be zero?

No, the distance between two charges can never be zero. According to Coulomb's Law, if the distance between two charges is zero, the force between them would be infinite. This is not physically possible as there is always some distance between two objects, no matter how small.

How is the distance between two charges measured?

The distance between two charges is typically measured in meters (m) or centimeters (cm). In most cases, a ruler, measuring tape, or other distance measuring tools are used to measure the distance between the two charges. In scientific experiments, more precise instruments such as a Vernier caliper or a micrometer may be used.

Does the distance between two charges affect the type of force between them?

The distance between two charges does not affect the type of force between them. The type of force is determined by the types of charges involved. If both charges are positive or negative, the force between them will be repulsive, and if one charge is positive and the other is negative, the force will be attractive.
