Answer:

0.000439077936334 m
Explanation:
q = Charge of electron = 
E = Electric field = 
= Permittivity of free space = 
d = Distance between plates = 2 cm (assumed)
m = Mass of electron = 
The beam consists of electrons which means it has negative charge this means the upper plates will be positive and the lower plate will be negative.
The direction is upper to lower lower plate.
= Permittivity of free space = 
Electric flux is given by

The charge per unit area on the plates is 
Deflection is given by

The deflection is 0.000439077936334 m
“Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom”
“Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.”
it’s B (because 20 Is smaller than 50)
Answer:
A) true
33) Osha data : true
34 ) False
Explanation:
A) Karl Landsteiner was the first to classify blood on the basis of modern theory .
33) OSHA ( Occupational Safety and Health Administration ) data relates to the safety measures that are taken by a unit or firm to avoid hazardous situation for their workforce.
34 ) There are as many as 150 points in an average finger prints that can be compared. Some country like England requires 16 point identification , some like France requires 17 points identification. So The statement is wrong.
