Question

state columns law in electrostatics​

Answer 1

Answer:

When two Charges are kept at Rest they attract or repel each other with a Electrostatic Force. Which is given by:

F=K q1 q2/r²

Where K = 1/4πE

It is Permittivity Of Free Space or Vaccum.

It's Value in Air is = 9 x 10^9

Rewriting it Expanding The Constant , The formula Becomes

F=$q1 \times q2 /4\pi E{r}^{2}$

Thanks for asking.

Answer 2

Answer:

colume law

Explanation:

colums law is states that when two charge having magnitudes q1 and q2 and distance between than is r than they experienced force

1. F is directly proportional to q1×q2
2. F is inversely proportional to squre of r
3. so, F =kq1×q2/r^2
4. hers k= 1/4pai€not
