Answer this pic question..

Answer 1

=> This question is based on coloumb's law.....

Answer 2

Answer:

Given:

2 charges are given. There distances are varied and a graph is plotted between Force and Distance .

To find:

The nature of the graph

Concept:

The force acting between 2 charges is Electrostatic Force.

As per Coloumb's Law ,the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them

$f \: \propto \: ( \dfrac{q1 \times q2}{ {r}^{2} } )$

Inserting a constant k:

$f = \:k ( \dfrac{q1 \times q2}{ {r}^{2} } )$

Since The charges have been specified, we can say that the charges are constants . So force will only be dependent on distance between the charges :

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \large{f \: \propto \: \dfrac{1}{ {r}^{2} }}}$

So, this Equation has the form of a. hyperbola.

Hence Option D) is correct.
