An electron and a proton enter the same velocity in a uniform magnetic field oriented vertically upwards. The two particles enter the field in parallel directions, in the same direction, perpendicular to the field lines. We know the mass of the electron m e = 1.9 kg 31 LA -10 and the mass of the proton mp = 67.1 kg 10 LA -27. Draw the trajectories of the particles and calculate the ratio between the radii of these trajectories.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
