Q 126 If a charge of 2C is moving with 5m/s enter at 30 degree in 3 T, calculate the force experienced by it A 10N В. 15N 20N 30N
Answers
Given info : A charge of 2C is moving with 5m/s enter at 30⁰ in 3T.
To find : calculate the force experienced by it
solution : force experienced by moving charge is given by, F = BqvsinФ
where, F is magnitude of force, B is magnetic field strength, q is charge of moving particle, v is velocity of that particle and Ф is angle between magnetic field strength and velocity of the particle.
here, q = 2C , B = 3T , v = 5 m/s and Ф = 30°
so, force = 3 × 2 × 5 × sin30° = 15 N
Thereforce, the force experienced by the charge particle is 15N.

Answer:
15
Explanation:
F=Bqvsin30°
F=(3)(2)(5)(sin30°)
:;(sin30°)=1/2
F=30(1/2)
F=15N
