What is the magnitude of the charge?

In summary, two 1.0g beads with equal charge are placed 50cm apart and accelerate at 150m/s2. The equations used are F = ma and F = kQQ / r2. The question is whether to use the total mass of 2.0g for both beads or just 1.0g. It is important to consider the objects the forces act on and their respective masses.

Two 1.0g beads are charged equally and placed 50cm apart. When released, they begin to accelerate at 150m/s2. What is the magnitude of the charge on each bead?

The equations I used:

F = ma
F = kQQ / r2

I was just wondering about the mass. Do I have to use the total mass (2.0g) for both beads or just the 1.0g?

have a careful think about what object(s) the force(s) act on and the mass of the object(s).
 

FAQ: What is the magnitude of the charge?

What is the magnitude of the charge?

The magnitude of the charge is a measure of the strength of an electric field or the amount of electric charge on an object. It is typically measured in units of Coulombs (C).

How is the magnitude of the charge calculated?

The magnitude of the charge can be calculated by using Coulomb's Law, which states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.

Can the magnitude of the charge be negative?

Yes, the magnitude of the charge can be negative. This signifies that the charge is negative in polarity and is attracted to positive charges.

How does the magnitude of the charge affect an electric field?

The magnitude of the charge directly affects the strength of an electric field. A higher magnitude of charge leads to a stronger electric field, while a lower magnitude of charge results in a weaker electric field.

What is the difference between magnitude of the charge and magnitude of the electric field?

The magnitude of the charge refers to the strength of the source charge, while the magnitude of the electric field refers to the strength of the electric field at a specific point in space. The two are related, but not the same.
