From F=BIL, Force exerted by the magnetic field=(2×1.69×10^-19×10^5)=3.2×10^-14, to find the direction of the force use fleming’s left hand rule, according to it the direction of the force is - y so the answer is E

Hi,

i believe you’ve confused the symbols, B outside is a dot and B inside is a cross

So the direction of the force is -y.

In your calculation 2 * 1,6 * 10⁵⁻¹⁹ = 3,2 * 10⁻¹⁴

Hope this helps!
