E=30 V/m E = 30 V / m is the maximum value of the electric field.

## How do you find the maximum electric field?

Since the voltage and plate separation are given, the electric field strength can be calculated directly from the expression E=VABd E = V AB d . Once the electric field strength is known, the force on a charge is found using F = qE.

## How do you find the value of an electric field?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r^{2}, where k is a constant with a value of 8.99 x 10^{9} N m^{2}/C^{2}.

## What is the maximum value of the electric field in the pulse?

The electromagnetic radiation from a pulse laser has a maximum electric field strength of 1.00 times 10 to the 11 volts per meter and the light is being emitted for 1.00 nanosecond, which is 1.00 times 10 to the minus 9 seconds.

## What is the maximum strength of the electric field of the wave?

The maximum strength of the magnetic field in a electromagnetic wave is 3.31E-6 T.

## How do you calculate electric field from electric potential?

If the electric potential is known at every point in a region of space, the electric field can be derived from the potential. In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V.

## What is EFQ Q?

E = F / q. The electric field strength (E) is defined as the amount of force exerted upon a test charge per unit of charge on the test charge (q).

## What is the value of k in electric field?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted k_{e}, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×10^{9} kg⋅m^{3}⋅s^{−}^{2}⋅C^{−}^{2}.

## What is electric field intensity?

A measure of the force exerted by one charged body on another. The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location. …

## How do you find the maximum magnetic field?

When an electromagnetic wave travels through magnetic and electric fields combined, then the relation between maximum magnetic field strength B and maximum electric field strength E can be given as, E=cB. E = c B . Here, c is the speed of light.

## What is the maximum magnitude of the electric field?

The maximum magnitude of the electric field in an electromagnetic wave is 0.0380 V/m.

## What is the maximum electric field strength in an electromagnetic wave that has a maximum magnetic field strength of about 10 times the Earth’s?
