Answer:
Explanation:
Given
Diameter(D)=21.5 cm
distance between plate=1.75 mm
and we know capacitance is
and we know charge is
Q=CV
and charge density (![\sigma [tex])[tex]=\frac{Q}{A}=\frac{\epsilon _0AV}{Ad}=\frac{\epsilon V}{d}](https://tex.z-dn.net/?f=%5Csigma%20%5Btex%5D%29%5Btex%5D%3D%5Cfrac%7BQ%7D%7BA%7D%3D%5Cfrac%7B%5Cepsilon%20_0AV%7D%7BAd%7D%3D%5Cfrac%7B%5Cepsilon%20V%7D%7Bd%7D)
Electric field(E)
Energy density
Energy desity
Energy desity![=\frac{1}{8\pi \cdot 9\times 10^9}\times \left [ \frac{12\times 10^3}{1.75}\right ]^2](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B8%5Cpi%20%5Ccdot%209%5Ctimes%2010%5E9%7D%5Ctimes%20%5Cleft%20%5B%20%5Cfrac%7B12%5Ctimes%2010%5E3%7D%7B1.75%7D%5Cright%20%5D%5E2)
Answer:
refraction
Explanation:
When waves, including light, pass through two media with different densities, the waves bend at the transition between the two media due to differences in speed and wavelength. Convex lenses bend (refract) light and concentrate it at one point called the focal point.

B. Magnetic force-attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges
may be described as the effect exerted upon either charge by a magnetic field created by the other.
6 / 3 = 2
So the reading on the voltmeter will be 2.
