Question

Which one is the answer ?
Please help !!

Answer 1

Answer:

7.2×10^-16 N

Explanation:

We know that,

                E=V/d

                  =9/2×10^-3

                  =4.5 × 10^3 N/C

∴E=F/q

 4.5×10^3=F/1.6×10^-19

∴F=4.5×10^3×1.6×10^-19

   =7.2×10^-16 N

So option D is the correct answer
