State Coulomb's law regarding the force of interaction between two point charge. Define the unit of charge from this law.

Define 1 coulomb of charge .

Two equal point charges ar placed in air 10 cm aprat and the force of interaction between them is 50 mg - wt . Determine the magnitude of the charges.

State Henry's law regarding the solublity of a gas in a liquid.

A 196 dyne force acts between two point charges separated by a distance 6 cm. If the magnitude of one charge is 4 times that of the other, calculate the charges on each.

The ratio of two charges is 2:3 and their distance of separation is 5 cm. If the force of attraction between them is 96 dyn, determine the magnitude the magnitude of the charges .

The presence of matter alters the net force acting between two charges. Explain.

State whether attraction can occur between two same kind of charges?

State ohms law explain it and define resistance from it?

Coulomb’s law related to electric charges is applicable when of the two charges-

Coulomb’s law for electrostatic force between two point charges and Newton’s Law of gravitational force between masses depends on the distance between the charges/ masses. (b) Estimate the accelerations of electron and proton due to the electrical force of their mutual attraction when they are 1overset@A(=10^(-10)m) apart? (m_p=1.67x10^(-27)kg,m_e=9.11x10^(-31)kg)
