Answer:
E = - dV / dx
Explanation:
The equipotential lines are lines or surfaces that have the same power, therefore we can move in them without carrying out work between equipotential lines, work must be carried out, therefore the electric field changes.
The electric field and the potential are related by
E = - dV / dx
therefore when the change is faster, that is, the equipotential lines are closer, the greater the electric field must be.

<span>If both surfaces are convex the lens is thicker at its center than its edges. A lens with one surface convex and one concave is called meniscus. Some lenses change the direction of the rays enough to cause the rays in a bundle to emerge convergent, that is, converging toward a common point. Whatever the mix of surfaces, if the lens is thicker at its center than its edges it is called a converging lens (having positive focal length). If it is thinner at its center than its edges it is called diverging (having negative focal length).</span>
Answer:
The units of frequency are hertz. As 1 hertz is equal to one cycle per second.
Amplitude is the maximum displacement of the waves or the distance from rest to crest and is measured in meters or centimeters or millimeters.
Answer:
Acceleration of the electron will be
Explanation:
We have given electric field
Charge on electron
So force in the electron
Mass of electron
Now according to newton second law
F = ma, here m is mass and a is acceleration
So
So acceleration of the electron will be
