Answer:
Explanation:
Given
The velocities of the protons are 400 m/s and 450 m/s
Mass of the Proton is
Since they travel in the opposite direction, therefore, their momentum cancels out each other.
Momentum is the product of mass and velocity
The direction of momentum is in the direction of proton having 450 m/s velocity.
Answer:
The frequency of the coil is 7.07 Hz
Explanation:
Given;
number of turn of the coil, N = 200 turn
area of the coil, A = 300 cm² = 0.03 m²
magnitude of magnetic field, B = 30 mT = 0.03 T
maximum value of induced emf, E = 8 V
The maximum induced emf in the coil is given by;
E = NBAω
E = NBA(2πf)
where;
f is the frequency of the coil
Therefore, the frequency of the coil is 7.07 Hz
