3the ans for the second is rong.Actually it is not an integer but we can neglect the fractional part it was abt 2x10-5.
Due to this we can always find the couloumb's law from gauss's law.
1)pls tell me the purpose of writing the constant K=1/4∩ε.
And couloumb had discoverd only its numerical value by his experiments am i rite.
2)The force between two charges is inversely proportional to r2 is the power is an integral or it is approximated.
3)Can couloumb's law can always be derivd from gauss's law even the power is not an integer.//

11. It is written in that manner because in many cases it simplifies calculations as 'pi' gets cancelled off. Yes, Couloumb had discoverd only its numerical value by his experiments.
2.Yes the power is an integral 2. The interesting thing to think about is that why all forces involve only the r2 term and why not r3, r4 etc. !
31Okay...i was not knowing that !... Coz i had heard that Couloumb had assumed it to be r2 and incidentally it came out to be correct!
But is it applicable to gravitational force too?
