Kinetic and potential energy
Answer:
The correct answer is the protons are accelerated upward.
Explanation:
Magnetic force causes a charged particle to move in a circular or spiral path. Protons in gigantic accelerators are kept in a circular path by magnetic force. A beam of protons is directed horizontally into the region between two bar magnets. The effect of the magnetic field on the protons is that the protons are accelerated upward.
<span>So we want to see what is the unit of electric current. The unit of electric current is 1A or 1 Ampere and it is defined as that current which would produce a force of 10^-7 N per metre lenght between two infinite parallel conductors separated by 1 meter of lenght. </span>
