An electron traveling parallel to a uniform electric field increases its speed from 2.0 * 107 m/s to 4.0 * 107 m/s over a distance of 1.2 cm. what is the electric field strength?

The electric field strength is

Explanation:

Given that,

Initial velocity

Final velocity

Distance = 1.2 cm

We need to calculate the acceleration

Using equation of motion

Put the value into the formula

We need to calculate the electric field strength

Using formula of electric force

Put the value into the formula

Hence, The electric field strength is

he . if i may ask what i your question exactly?

explanation:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
