In electrostatic equilibrium, the electric field inside a conductor is zero.

In electrostatic equilibrium, the electric field inside a conductor is zero.

In electrostatic equilibrium, the electric field inside a conductor is zero.

The electric field strength E ∝ 1/r², so if distance is tripled, the field strength becomes 1/9 of the original.

The electric potential decreases as you move away from a positive charge.

When a charge moves against an electric field, its electric potential energy increases.

The electric potential energy of a system of charges decreases when they are brought closer together, especially if they are of opposite signs.

The electric potential energy increases as like charges repel each other.

The energy stored in a capacitor is given by U = 1/2 C V². If the voltage is doubled, the energy increases by a factor of four.

During a reversible isothermal expansion, the entropy of the system increases as the gas expands and does work on the surroundings.

In a reversible process, the total entropy of the system and surroundings remains constant.

In a spontaneous process, the entropy of a system increases.

The second law of thermodynamics states that the entropy of an isolated system always increases.

In a p-type semiconductor, the Fermi level moves up towards the valence band due to the increased hole concentration.

When a lens is immersed in a medium with a higher refractive index, its effective focal length decreases due to the reduced refractive power.

The focal length of a lens decreases when immersed in a medium with a higher refractive index than air.

As damping increases, the frequency of the damped oscillator decreases.

The frequency of oscillation in a damped system is lower than that of an undamped system due to energy loss.

Fringe width (β) is inversely proportional to the distance to the screen (D). If D is halved, the fringe width decreases.

When the Wheatstone bridge is balanced, the potential difference across the galvanometer is zero, resulting in zero current.

The gravitational force is directly proportional to the product of the masses. If one mass is tripled, the force also triples.

The gravitational force is inversely proportional to the square of the distance. If the distance is tripled, the force becomes 1/(3^2) = 1/9 of the original force.

The gravitational force is directly proportional to the product of the masses. If one mass is tripled, the force also triples.

The gravitational force is directly proportional to the product of the masses, so tripling one mass triples the force.

The gravitational force is directly proportional to the product of the masses, so tripling one mass triples the force.

The gravitational force on a satellite decreases as it moves further away from the Earth, following the inverse square law.

The gravitational force on a satellite decreases as it moves to a higher orbit due to the inverse square law of gravitation.

The gravitational force decreases with the square of the distance from the center of the Earth. If the altitude is doubled, the distance from the center of the Earth becomes R + 2h, and the force becomes weaker by a factor of four.

The gravitational potential decreases as you move away from a mass.

The gravitational potential decreases as you move away from a massive body.
