A proton of charge 1.6 x 1019C is projected into a uniform magnetic field of flux density with a constant speed of 1.6 x 106ms-1, calculate the magnitude of the force exerted on it by the field
A
0.0N
B
2.0 x 10-21N
C
1.3 x 10-17N
D
5.1 x 10-14N
correct option: c
F = Bqv = 5.0 x 10-5 x 1.6 x 10-19 x 106
= 1.3 x 10-17
= 1.3 x 10-17
