Answer:
243 N
Explanation:
The formula for electromagnetic force is F= Kq1q2/r^2
where r is the distance between the charges, if the distance between the charges is reduced by 1/3 then F will increase by 9 [(1/3r)^2 becomes 1/9r which is 9F] so 27*9 is 243N
0.42
444.99
it is 12.15 km
1215 km ÷1000
=12.15

Answer: 1160 m
Speed = distance / time. Therefore, 40 m/s = d / 29 s → d = 1160 m.
