Answer:
F = 3.84*10^-34N ^j
Explanation:
In order to calculate the magnetic force on the electron you use the following formula:
(1)
q: charge of the electron = -1.6*10^-19C
B: magnitude of the magnetic field = 0.80T
v: speed of the charge = 3.0*10^5 m/s
The direction of the motion of the electron is in the +i^ direction (+x direction). The magnetic field is in the +^k direction (+z direction).
The cross product between these unit vectors, by taking into account the minus sign of the charge, is given by:
-^i X ^k = ^j
The magnetic force is in the ^j direction (+y direction).
The magnitude of the magnetic force is:
The magnetic force on the electron has a magnitude of 3.84*10^-34N in the +y direction

Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.
Fusion could be the world's answer to clean unlimited amounts of energy.
Fusion is extremely difficult to contain and maintain here on earth.
Explanation:
Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.
The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.
- As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
- it is known that nuclear fusion produces far more energy than fission reaction.
- It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
- The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.
