Question

Answer the following questions :-

1. Show does the force between two point charges change if the dielectric constant of the medium in which they are kept increase?

2. A charged rod Pattracts rod R Where as Repels another charged rod Q. What type of force is developed between Q and R?

3. Which physical quantity has its S.I unit (1) Cm (2) NC

4. Define one coulomb?​

Answer 1

Answer:

1. Show does the force between two point charges change if the dielectric constant.

of the medium in which they are kept increase? Force is inversely proportional to the dielectric constant.

Therefore the force will decrease as dielectric constant increases.

2.

3. Clearly dipole moment has the unit Coulomb meter (Cm) in S.I. unit of electric field is N/C i.e newton per coulomb.

4. The coulomb, also written as its abbreviation 'C', is the SI unit for electric charge.

One coulomb is equal to the amount of charge from a current of one ampere flowing for one second.

One coulomb is equal to the charge on 6.241 x 1018 protons. ...
