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

Answer:
the extension recorded by the student would be smaller than the actual extension of the spring
It mimics the real world accurately
Explanation:
Experiments conducted in the field clearly presents the real world at it is to the scientist. Hardly can any part be controlled precisely and this gives a near to perfect scenario.
- In the laboratory, for example, an organism is isolated from its environment and might not fully display its natural instinct and physiological capabilities.
- Most laboratory set up are driven towards a model instead of real life settings.
