Solution

g i v e n u = 0 v = 5 \times 10^{6} m / s s = 1 c m = 0.01 m n o w, v^{2} - u^{2} = 2 a s \Rightarrow a = \frac{v^{2} - u^{2}}{2 s} = \frac{{(5 \times 10^{6})}^{2}}{2 \times 0.01} = 12.5 \times 10^{14} m / s^{2} n o w, f o r c e = F = m a = 9.1 \times 10^{- 31} \times 5 \times 10^{6} = 113.75 \times 10^{- 17} N = 1.1375 \times 10^{- 15} N
