An electron is accelerqated in the uniform field betwen two parallel charged oplates. the separation of the plates is 1.20 cm

The speed of electron is

Explanation:

Given that,

Separation of the plate = 1.20 cm

Suppose the field is .

If the electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate.

What the speed does it leave the hole?

We need to calculate the acceleration

Using formula of electric force

We need to calculate the speed of electron

Using equation of motion

Put the value of acceleration in the formula

Put the value into the formula

Hence, The speed of electron is

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6
