Answer:

a) 28.8×10^10N/C

b) 14.4×10^10N/C

c) Force on electron particle= 46.13×10^-9N

Force on the alpha= 146.08×10^-9N

Explanation:

Using the equation, E = kq/r^2

a) E = (8.99×10^9)×(3.2×10^-19) / (10^-10)^2

E = 28.8×10^-9N/C

b) E = kq/r^2

E = (8.99×10^9)×(1.602×10^-19)/(10^-10)^2

E= 14.4×10^10N/C

c) Felectron= E× q = (28.8×10^10)×(1.602×10^-19)

Felectron= 46.13×10^-9N

Force F on alpha = E× q= 14.4x10^10)×(3.2×10^-19)

F alpha= 146.08 ×10^-9N
