Question 1

Point Charges

Answer 1

For any point outside a spherical conductor the charge on the sphere may be considered to act as a point charge at the centre of the sphere

Question 2

Coulombs Law

Answer 2

The force between two point charges is proportional to the product of the charges and inversely proportional to the square of it’s seperation

Question 3

Electric Field Strength

Answer 3

It is defined as the force per unit charge acting on a small stationary positive charge placed at that point

Question 4

Electric Field

Answer 4

It is defined as the force per unit positive charge

Question 5

Electric Potential

Answer 5

At a point in an electric field is defined as the workforce per unit positive charge in bringing a small test charge from infinity to the point
