a)
Generally the equation for Force on 
due to 
is mathematically given by
Where
B_2=Magnetic field current by
Therefore
b)
Generally the equation for Force on due to 
is mathematically given by
Where
B_1=Magnetic field current by
Therefore
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
Answer:
C. Both technicians A and B
Explanation:
From the physical definition, power is defined as the rate of a body doing work. It is expressed as
P = w/t watts
Where
w - is the work done or the energy of the system in joules
t - time
The unit of power is represented in watts.
Whenever there is a rate of change of energy in the system, it accounts for the efficiency of the power of the system.
Hence, the statements of both technicians are correct.
