What is the purpose of the magnetic field in a cathode ray tube?

Physics
1 answer:
andre [41]2 years ago
4 0

Answer:

In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged.

Explanation:

Hello!

To solve this problem we will use the following steps

1. We will use the equation that defines the distance between two points in order to find the distance from the origin to each of the points that the problem asks for.

d=\sqrt{x^2+y^2}

x= horizonalt component

y=vertical component

d=distance

i)

x=0

y=6

d=\sqrt{0^2+6^2}=6m

ii)

x=6

y=0

d=\sqrt{6^2+0^2}=6m

iii).

x=6

y=6

d=\sqrt{6^2+6^2}=8.48m

2.we calculate the voltage at each point using the equation that relates the distance the voltage and the electric field

V=Ed

where

V=EPD= the electric potential difference

E=electric field  magnitude=6.8 × 10^5 N/C.

d=distance

i)

V=Ed=(6.8 × 105 N/C.)(6)=4080000V

ii)

i)

V=Ed=(6.8 × 105 N/C.)(6)=4080000V

iii)

i)

V=Ed=(6.8 × 105 N/C.)(8.48m)=5766400v
