Answer:
(A)
(B)
Explanation:
Given:
- initial energy of hydride ion,
- final energy of hydride ion,
- mass of ion (=mass of proton, we know),
- magnetic field,
(A)
kinetic energy of 5 MeV ion:
(B)
Radius of ion when having energy 5.0 MeV:
We know:
..................................(1)
also,
..........................(2)
where:
F= force on the charge
q= quantity of charge on the particle (an electron in this case)
m= mass of the charged particle
B= magnetic field in which the charge is projected
r= radius of the path circulation of the charge
v= velocity of the charge at the instant
From eq. (1) & (2)
putting the reaspective values:
Answer:
emf=-10V
Explanation:
the emf can be calculated by using the expression
where Ф is the magnetic flux and S is the area of the turns.
we can take that in one half of the period, we have the maximum and minimum of the flux. Hence
Thus, we have
