In the simulation above the red ball's motion is always the same (5.00 m/s) while the blue ball's motion can be modified by chan
ging the value of its acceleration (that is set by the slider). Note that for each part of this question you can use the simulation to help guide you, and in some cases to check your answer, but you should calculate numerical answers based on principles of physics rather than taking numbers directly from the simulation.
(a) What would the blue ball's acceleration have to be for the blue ball to win the race by a distance of 15.0 meters?
For the remaining questions set the acceleration of the blue ball to be 5.70 m/s2.
(b) How far is the second ball from the finish line when the first ball reaches the line?
(c) If the motion continues for both balls until the second ball reaches the finish line, what is the distance between the two balls at that time?

Answer:
1) The magnetic field outside the loop is zero.
In region III the magnetic fields due to the two wire loops point in the opposite direction andhence cancel each other. Therefore the magnetic field is zero in region I, III and V

Answer:
(a) momentum of photon is 1.205 x 10⁻²⁷ kgm/s
velocity of electron is 1323.88 m/s
momentum of the electron is 1.205 x 10⁻²⁷ kgm/s
(b) momentum of photon is 1.506 x 10⁻²⁷ kgm/s
velocity of electron is 1654.85 m/s
momentum of the electron is 1.506 x 10⁻²⁷ kgm/s
(c) The momentum of the photon is equal to the momentum of the electron
Explanation:
(a)
wavelength of green light, λ = 550 nm
momentum of photon is given by;
velocity of electron is given by;
momentum of the electron is given by;
p = mv
p = (9.1 x 10⁻³¹) (1323.88)
p = 1.205 x 10⁻²⁷ kgm/s
(b)
wavelength of red light, λ = 440 nm
momentum of photon is given by;
velocity of electron is given by;
momentum of the electron is given by;
p = mv
p = (9.1 x 10⁻³¹) (1654.85)
p = 1.506 x 10⁻²⁷ kgm/s
(c) The momentum of the photon is equal to the momentum of the electron.
