Hi
The magnitude of the magnetic force on a charg particle is F = |q| v B sin θ
Here q = charge on a proton = 1.602 x 10^-19 C
v = 10^7m/s
θ = 90
B = 10T
Substituting all these values in the expression for F, we get
F = 1.602 x 10^-19C x 10^7 m/s x 10 T sin 90°
= 1.6 x10^-11 N
c option
hope it help
