Q.No.1

What fundamental property of the electron did Millikan's oil drop experiment primarily measure?

Q.No.2

What was the significance of Millikan observing that charges on oil drops were always integer multiples of a fundamental value?

Q.No.3

An electron moving perpendicular to a uniform magnetic field will follow what type of path?

Q.No.4

In Millikan's oil drop experiment, what two forces were balanced when an oil drop was suspended motionless?

Q.No.5

If an electron enters an electric field perpendicular to the field lines, what shape will its path typically take?

Q.No.6

What is the magnetic force on an electron if its velocity is parallel to the magnetic field lines?

Q.No.7

J.J. Thomson's experiment in 1897 was crucial for discovering which property of the electron?

Q.No.8

In Thomson's experiment, how was the velocity of the electron beam determined?

Q.No.9

Thomson's measured e/m ratio for cathode rays was much larger than that for hydrogen ions. What did this suggest?

Q.No.10

What is the approximate value of the elementary electric charge (e) as determined by Millikan?
