Assertion : Electrostalic forces are attractive as well as repulsive in nature.
Reason : Charges are positive and negative in nature.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

C

Explanation

Mass comes in one variety, there is not negative mass, but charge comes in two varieties (positive and negative). That is why gravitational force is always attractive and electromagnetic forcce can be attractive or repulsive. Gravitational force dominates terrestrial phenomena and electric force is largely zero because matter is mostly electrically neutral. i.e., net charge is zero.
