Question

Assertion :The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them. Reason: Electrostatic force is analogous to gravitational force

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

The assertion is correct because electrostatic force between two-pint charges is

$F=\frac{1}{4\pi {\epsilon }_0}\frac{q_1{q}_2}{r^2}$

where $F$ is proportional to the product of two charges and inversely proportional to the distance between them.

Reason is also correct because gravitational force is $Fg=\frac{G{m}_1{m}_2}{r^2}$

where $G=$ gravitational constant $m_1$ and $m_2$ are two masses.

$r=$ separation between masses

$Fg$ is similar to electrostatic force $F$.

But the reason is the correct explanation for an assertion.
