    What is the electric field direction at point (0, R)?

    It points away from the positive charges.

    How does the electric potential at point (0, R) compare to infinity?

    It is higher than zero due to nearby charges.

    What happens to the electric field when point charges are moved?

    The field configuration changes based on their new positions.

    Which potential is higher, V1 or V2?

    The one closer to positive charges is higher.

    What is the effect of a dielectric on capacitor charging?

    It increases the capacitance and reduces the electric field.

    What is the relationship between voltage and charge in a capacitor?

    Voltage is directly proportional to charge stored.

    How does the current through resistors R1 and R2 depend on their arrangement?

    In series, the same current flows; in parallel, it divides.

    What is the significance of the electric field direction in a circuit?

    It determines the direction of current flow.

    What happens to the magnetic field when a charged particle moves through it?

    It experiences a force perpendicular to both velocity and field.

    How does the speed of a particle affect its trajectory in a magnetic field?

    Higher speeds result in larger radius of curvature.

    What is the effect of a magnetic field on a stationary charge?

    It exerts no force on the charge.

    What is the relationship between the induced current and the changing magnetic field?

    Induced current flows in a direction to oppose the change.

    What determines the direction of induced current in a loop?

    Lenz's law states it opposes the change in magnetic flux.

    What is the role of resistance in an electrical circuit?

    It opposes the flow of electric current.

    How does the angle of a conductor in a magnetic field affect induced EMF?

    The induced EMF is maximum when perpendicular to the field.
