The electric field between the plates of the cathode ray tube of an older television set can be as high as 2.5x104 N/C. Determine the force (use dimensional analysis!) and resulting acceleration of an electron?

(a)

(b)

Explanation:

Parameter given:

Electric field, E =

(a) Electric force is given (in terms of electric field) as a product of electric charge and electric field.

Mathematically:

Electric charge, q, of an electron =

(b) This electrostatic force causes the electron to accelerate with an equivalent force:

F = -ma

where m = mass of an electron

a = acceleration of electron

(Note: the force is negative cos the direction of the force is opposite the direction of the electron)

Therefore:

Mass, m, of an electron =

=>

The acceleration of the electron is

your answer is yx

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
