Description: Two point charges Q1 and Q2 are 3 m apart, and their sum of charges is 10 μC. If force of attraction between them is 0.075 N, then the values of Q1 and Q2 respectively, are &. 5 μC, 5 μC b. 15 μC,-5 μC c. 5 μC, 15 μC d. -15 μC, 5 μC

step 1 So it is given that Q1 plus Q2 equal 10 and K, Q1, Q2 upon R square equals minus 0 .075. So K is

Key Concepts

Charge Sign and Interaction

The sign of a charge determines the nature of the interaction between charges. Like charges repel while opposite charges attract, which is a critical consideration when determining whether the force between two charges is attractive or repulsive. This concept is essential in solving problems where the observed force is specified as either an attraction or a repulsion, thereby narrowing down the possible values of the individual charges.

Coulomb's Law

Coulomb's Law provides the quantitative description of the electric force between two point charges. It states that the magnitude of the force is directly proportional to the product of the absolute values of the charges and inversely proportional to the square of the distance between them. This fundamental law is used to analyze interactions in electrostatics and to solve problems involving point charges.
