A convex mirror is used as a rear-view mirror in vehicles. The image formed is always:

Two point charges of +4 μC and −4 μC are placed 0.2 m apart in vacuum. The magnitude of the electric force between them is: (Take k = 9 × 10⁹ N m² C⁻²)

The energy of a photon of frequency ν is (where h = Planck's constant):

A series LCR circuit has L = 4 H and C = 25 μF. The resonant frequency of the circuit is:

The SI unit of magnetic flux is:

A simple pendulum of length L has a period T on Earth. If the pendulum is taken to a height h above the Earth surface where the gravitational acceleration becomes (2/3)g, its new period is:

A satellite orbits very close to the surface of Earth (neglecting atmospheric drag). If Earth's radius is 6400 km and g = 10 m/s², the orbital period of this satellite is approximately:

A proton and an alpha particle are accelerated through the same potential difference V. The ratio of their de Broglie wavelengths (lambda_p/lambda_alpha) is:
