What is the method to find the electric field between the plates in a parallel plate capacitor?
To find the electric field between the plates in a parallel plate capacitor, you can use the formula E V/d, where E is the electric field strength, V is the voltage across the plates, and d is the distance between the plates.

The magnitude of the uniform electric field between the plates can be calculated using the formula E = V/d, where E is the electric field, V is the voltage, and d is the distance between the plates. Plugging in the values, E = 20 kV / 1.9 cm = 10526.32 V/m (or N/C).
A rod of length L has total charge Q distributed uniformly along its length it's then bent in the shape of a semicircle find the magnitude of the electric field at the centre of semicircle?
At the center of the semicircle, the electric field due to the straight part of the rod will cancel out because of the symmetry. The electric field at the center of the semicircle is only due to the curved part, so you can treat the semicircle as an arc of a circle with charge distributed along its length. You can then calculate the electric field using the formula for the electric field of a charged arc of a circle.

To find the electric field near the charged plate, you can use the formula for electric field due to a charged disk: ( E = \frac{\sigma}{2\epsilon_0}(1 - \frac{z}{\sqrt{z^2 + r^2}}) ), where ( \sigma ) is the charge density, ( \epsilon_0 ) is the permittivity of free space, ( z ) is the distance from the center of the disk and ( r ) is the radius. Substituting the values given, you can find the electric field magnitude near the plate.

How to find the electric field at a point in a given system?
To find the electric field at a point in a given system, you can use Coulomb's law or Gauss's law. Coulomb's law involves calculating the electric field due to individual charges in the system, while Gauss's law allows you to find the electric field by considering the total charge enclosed by a Gaussian surface around the point of interest. By applying these principles, you can determine the electric field strength and direction at a specific point in the system.
