Answer 2

QUESTION:- Which formula below correctly states Coulomb's Law?

OPTIONS:-

`A. \: \: \: \: F = kqq/r^ 2 \\B. \: \: \: \: F = kqq/r \\C. \: \: \: \: F = qq/kr^ 2 \\D. \: \: \: \: F = kr^2 /qq \\`

ANSWER:-

F is directly proportional to the product of the charges

`F∝qq`

F is inversely proportional to the square of the distance between them

`F∝ \frac{1}{ {r}^(2) }`

from above 2 equation:-

we get:-

`F∝ \frac{qq}{ {r}^(2) }`

To remove proportionality sign we use constant for this case we r using constant k

`F = \frac{Kqq}{ {r}^(2) }`

So your answer is :-

OPTION A.

`F = \frac{Kqq}{ {r}^(2) }`
