In summary, two 10-cm-diameter charged rings with opposite charges of -17nC and +17nC are placed 25cm apart. The magnitude of the electric field at the midpoint between the two rings is 2.2E4, using the equation (E1)z=ZQ1/4πε0(z^2+r^2)^(3/2) with incorrect values for z and r. A -1.0 nC charge placed at the midpoint would experience a force of unknown magnitude, as the correct values for z and r have not been provided.

A.What is the magnitude of the electric field E⃗ at the midpoint between the two rings?B.What is the magnitude of the force F⃗ on a -1.0 nC charge placed at the midpoint?
Express your answer to two significant figures and include the appropriate units.

Homework Equations


(E1)z=ZQ1/4πε0(z^2+r^2)^(3/2)

The Attempt at a Solution


((9E9)(.10)(-17E-9))/((.10)^2+(.50)^2)^3/2= 2.2E4.
Unfortunately
this is not the answer any help?

You don't seem to have correctly matched up the z and r variables in the equation to the given numbers. What values for z and r have you used?
 

1. What is magnitude in science?

Magnitude in science refers to the measure of the strength or size of a physical quantity or phenomenon. It can also be described as the degree or intensity of a specific characteristic or property.

2. How do you calculate magnitude?

The specific method for calculating magnitude will depend on the specific physical quantity or phenomenon being measured. In general, magnitude can be calculated using mathematical equations or formulas that take into account relevant variables and units of measurement.

3. What is the difference between magnitude and direction?

Magnitude and direction are two components of a vector quantity. Magnitude refers to the size or strength of the vector, while direction refers to the orientation or angle of the vector. Both magnitude and direction are necessary to fully describe a vector.

4. What are the units of magnitude?

The units of magnitude will vary depending on the specific physical quantity being measured. For example, magnitude of force is typically measured in Newtons (N), while magnitude of electric charge is measured in Coulombs (C).

5. How does magnitude relate to scale and measurement?

Magnitude is often used to indicate the size or scale of a measurement. For example, the magnitude of an earthquake can be used to determine its intensity on the Richter scale. In general, magnitude plays a significant role in accurately measuring and understanding various phenomena in science.
