Answer:
(a) (B)
Explanation:
We have given the the speed of the electron =10^6 m/sec
The time period of the electron is given by where r is the Bohr radius, which is equal to
So time period
(A) We know that current
(B) Magnetic moment is given by , where I is current and A is area
So

Answer:
The maximum speed is 21.39 m/s.
Explanation:
Given;
radius of the flat curve, r₁ = 150 m
maximum speed, = 32.5 m/s
The maximum acceleration on the unbanked curve is calculated as;
the radius of the second flat curve, r₂ = 65.0 m
the maximum speed this unbanked curve should be rated is calculated as;
Therefore, the maximum speed is 21.39 m/s.
