Sources of error in a diverging lens experiment

Snezhnost [94]

Answer:

Lens and the virtual image was the image distance. Error was made when measuring the distances and determining values that were reasonable for focal length, so this error was accounted for when calculating the focal length by adding or subtracting uncertainties from the values.Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). 5.

You connect a 9V battery to a capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2.0 mm. W

mel-nik [20]

The charge on the positive plate is 1.734* $10^{-12}$ C

Given,

V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85* $10^{-12}$

We know C=∈ * $\frac{A}{G}$ = 8.85* $10^{-12}$ * $\frac{\pi *0.066^{2} }{0.002}$ =19.275* $10^{-12}$ F

Also, Q = C V = 19.275* $10^{-12}$ * 9 = 1.734* $10^{-12}$ C

<h3>Charge </h3>

When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
