According to Coulomb's Law, the electrostatic force between two point charges is inversely proportional to what?
The sum of the charges
The square of the distance between them
The product of the charges
The distance between them
What happens to a body when it loses electrons?
It gains mass
It becomes positively charged
It remains neutral
It becomes negatively charged
What is the dielectric constant also known as?
Charge density
Electric potential
Electric field strength
Relative permittivity
What is the formula for electric field intensity due to a point charge?
E = F / q
E = q / (4πε0r^2)
E = V / d
E = k * q / r^2
What is the nature of electric charge?
Scalar quantity
None of the above
Vector quantity
Both vector and scalar
What is the electrostatic potential energy of a two-charge system?
U = q1 * q2 / (4πε0 * r12)
U = q1 + q2
U = q1 * q2 * r
U = 0
What is the relationship between electric field and potential difference?
E = V/r
E = V^2
E = dV/dr
E = -dV/dr
What is the property of electric lines of force?
They are always circular
They indicate the direction of the electric field
They are always straight lines
They can cross each other
