Answer:
The direction of force is along negative Z axis and the magnitude of force is
6.4 x 10^-14 N.
Explanation:
q = - 1.6 x 10^-19 c
vx = 5 x 10^5 m/s, vy = 3 x 10^5 m/s, B = 0.8 T along Y axis
The velocity vector is given by
v = 5 x 10^5 i + 3 x 10^5 j
B = 0.8 j
Force on a charged particle place in a magnetic field is given by
F = q (v x B)
F = -1.6 x 10^-19 {(5 x 10^5 i + 3 x 10^5 j) x (0.8 j)}
F = - 1.6 x 10^-19 (5 x 0.8 x 10^5 k)
F = - 6.4 x 10^-14 k
The direction of force is along negative Z axis and the magnitude of force is
6.4 x 10^-14 N.
To solve this problem we must simply resort to Newton's second law as well as the relationship between pressure and force as a physical unit applied in a given area.
In mathematical terms the Weight can be expressed as
Where,
m = mass
g = Gravitational Acceleration
We have the mass and the gravitational acceleration therefore the Weight is
Replacing we have
In this way the pressure exerted according to the active Area is,
Therefore the pressure difference between the lower and upper surface of the wings is 9.14kPa
is this the skater one? If so, it does support the law of conservation of energy because at the top of the ramp the skater has the same amount of potential energy their total energy and as the skater goes down the ramp their potential energy lowers as their kinetic energy rises.
