Good luck and have a nice day! :D
Answer:
the sign of these carriers is POSITIVE
Explanation:
In the effect, he found the charge carriers that were subjected to two forces, one electric and the other magnetic.
F = F_e + F_m = q E + q v x B
bold indicates vectors
The electric field goes to the east, therefore the current also has this direction, the vector product of the velocity of the charge carriers towards the east and the magnetic field upwards, using the right hand rule a magnetic force is created towards the north if the carriers are positive.
In the exercise they indicate that the north side has a higher potential than the south side, therefore there must be an accumulation of carriers on this side that create an electric field (Hall) that is put to the magnetic force until reaching equilibrium when the total force is zero.
Therefore the sign of these carriers is POSITIVE
Answer:
F = 2500N
Explanation:
F = ma
You're given m=25kg and a=100m/s²
Plug it in
F = (25)(100)
F = 2500N
Explanation:
According to Newton's second law of motion:
Force is directly proportional to
Change of momentum/time taken
Change of momentum= mv-mu
where m is mass, u is initial velocity and v is final velocity. so,
F∝mv-mu/t
F∝m(v-u)/t
F∝ma (a=v-u/t)
F=kma where k is a constant
In SI units the value of k will become one so the equation will be:
F=ma
