Answer:
magnitude of the magnetic field 0.692 T
Explanation:
given data
rectangular dimensions = 2.80 cm by 3.20 cm
angle of 30.0°
produce a flux Ф = 3.10 ×
Wb
solution
we take here rectangular side a and b as a = 2.80 cm and b = 3.20 cm
and here angle between magnitude field and area will be ∅ = 90 - 30
∅ = 60°
and flux is express as
flux Ф =
.................1
and Ф = BA cos∅ ............2
so B =
and we know
A = ab
so
B =
..............3
put here value
B =
solve we get
B = 0.692 T
The answer is 2500 newtons. F = M * A, so 500 kg x 5 m/s = 2500 newtons.
The correct answer is: 1792g or 1800g.
(When you round it)
Answer:
or 
23.4843749996 m
Yes
Explanation:
E = Electric field = 
c = Speed of light = 
m = Mass of proton= 
q = Charge of electron = 
Acceleration is given by

Dividing by g

The acceleration is
or 

The distance is 23.4843749996 m
The gravitational field is very small compared to the electric field so the effects of gravity can be ignored.
