An electron moving at 4.00×103 m/s in a 1.25-T magnetic field experiences a magnetic force of 1.40×10−16 N . What angle does the velocity of the electron make with the magnetic field?

i think the answer would be b

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

god i hope this !
