Question

exam 1: atomic theory/structure
which letter shows the correct path that the negatively charged cathode ray laser traveled?
cathode anode
n
s
fluorescent screen
magnet
a
b
c

Explanation:

Step1: Recall magnetic - force on charge

A negatively - charged particle in a magnetic field experiences a force given by the right - hand rule.

Step2: Apply right - hand rule

Point fingers in direction of velocity, curl towards magnetic field direction, and thumb gives force direction. For a negative charge, the force is opposite. The cathode ray (negatively charged) will be deflected upwards.

Answer:

A. A
