In the Cathode ray tube experiment, a negatively charged object is placed at position - C in figure below. Predict what will happen based on your knowledge of Thomsons's experimental results with cathode rays and their charge.



a
Cathode rays are positively charged so they will be attracted to the negative charge and bend towards C and then disappear
b
The cathode rays will bend towards A because it is repelled by the negative charge at C
c
The cathode beams will keep moving towards be as it is neither attracted or repelled by the negative charge
d
The cathode rays will bend towards C because it is attracted by the negative charge at C

Answer: b.

Reason: Thomson showed cathode rays are negatively charged (electrons). A negative object at C will repel the rays, so the beam will bend away from C and toward A.
