Answer:
1.
-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
Step-by-step explanation:
We are given that magnetic deflection
We have to match each symbol in formula with what it represents.
In this formula
Deflection force
q=Charge of particle
v=Velocity of charge
B=Perpendicular magnetic field strength
Therefore,
1.
-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
