Question

Determine the electric field (in N/C) required to give the maximum possible deviation angle. (Enter the magnitude.)

Answer 1

Maximum angle = 3.43⁰

Step-by-step explanation:

Say that you are given the following information:

vertical distance between the charge plate = 0.03 m

length of the plate = 0.5 m

velocity of the electrons = 5 × 10⁶ ms⁻¹

the maximum angle is given by the formula:

`tan\theta _(max) = (d)/(l)`

where d = vertical distance between the charge plate

l = length of the plate

substituting the values l and d gives:

`tan\theta _(max) = (0.03)/(0.5)`

maximum angle,
`\theta _(max) = (0.03)/(0.5)`

`\theta _(max) = tan^(-1) ((0.03)/(0.5) )`

= 3.43⁰
