Answer:
Explanation:
There are two forces acting on the oil drop:
- The force of gravity, downward, given by
where m is the mass of the drop and g is the acceleration due to gravity
- The electric force, upward, given by
where q is the charge of the oil drop and E is the magnitude of the electric field
The oil drop remains stationary, so the two forces are balanced:
where
Substituting into the previous equation and solving for q, we find the charge of the oil drop:
Answer:
Explanation:
a. Is the sphere charged negatively or positively?
The sphere us negatively charged. In a Millikan type experiment, there will be two forces that will be acting on the sphere which are the electric force which acts upward and also the gravity which acts downward.
Because the upper plate is positively charged, there'll what an attractive curve with an upward direction which will be felt by the negatively charged sphere.
b. What is the magnitude of the electric field intensity between the plates?
The magnitude of the electric field intensity between the plates is 18400v/m.
C. Calculate the magnitude of the charge on the latex sphere.
The magnitude of the charge on the latex sphere hae been solved and attached
d. How many excess or deficit electrons does the sphere have?
There are 5 excess electrons that the sphere has.
Check the attachment for further explanation.

Astronomers learn about the internal structure and evolution of stars by using spectroscopy and observing their luminosity.
New stars form in nebulae, interstellar gases and dust clouds leftover from supernovas.
Supernovas are the results of stars running out of its nuclear fuels.
The lifespan of a massive star is shorter than a star like the Sun because massive stars have very high pressures and temperatures at their cores and therefore burn their nuclear fuels faster. Stars grow larger as they age.
