Question # 1
Describe the force or forces on a positive point charge when placed between parallel plate,with similar and equal charges.
- Ans 1: When a positive point charge is placed between parallel plates with similar and equal charges,then the electric field intensity due to one plate is equal in magnitude but opposite in direction of electric intensity due to other plate.So the value of resultant electric field intensity E is zero,Hence the net force on the positive charge is zero,Thus is will remain at rest.

Question # 1
State coulomb's law.
- Ans 1: It states that the force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charge and inversely proportional to the square of the distance between them.
