Aproton enters a magnetic field of flux density 1.5 Wb/m2 with a speed

1.	Aproton enters a magnetic field of flux density 1.5 Wb/m2 with a speed of 2x 107 m/s at angle of 30° with the field. The force on the proton will be-(a) 0.24 x 10-12 N (b) 2.4 x 10-12 N (c) 24 x 10-12 N (d) 0.024 x 10-12 N
Answer» (b) 2.4 x 10^-12 N F = Bqv sin θ =1.5 x 1.6 x 10^-19x 2 x 10⁷x sin 30° = 2.4 x 10^-12N

Answer»

(b) 2.4 x 10^-12 N

F = Bqv sin θ =1.5 x 1.6 x 10^-19x 2 x 10⁷x sin 30°

= 2.4 x 10^-12N
