Answer:
(A) 0.8 kgm/s
Explanation:
because of the even ground it would only slow down
Answer:
C has 5 electrons
Explanation:
Given:
The data acquired from the experiment performed by Millikan:
Q_a = 3.20 x10^{-19} C
Q_b = 4.80 x10^{-19} C
Q_c = 8.00 x 10^{-19} C
Q_d = 9.60 x 10^{-19} C
Find:
How many Electrons were present in drop C
Solution:
It is known that the charge of an electron e = 1.602 *10^-19 C / electron.
Hence the number of electrons n in drop C will be:
n = Q_c / e
n = 8.00 x 10^{-19} / 1.602*10^-19
n = 4.99 = 5 electrons
Answer: The drop C contains 5 electrons.
