    The time period T of a satellite in orbit depends on the radius of its orbit and the mass of the central body, such as the Earth. It is derived from the balance between gravitational force and the centripetal force required for circular motion.

    The time period can be expressed in terms of the orbital radius R + h and the gravitational constant G as:

    T proportional to √((R + h)³/(GM))

    This relationship shows that the time period is determined solely by the orbital radius and the mass of the central body. Importantly, the satellite’s mass does not appear in the formula, indicating that the time period is independent of the satellite’s mass.

  2. In a series LCR circuit, the voltages across the inductor (Vl = 20V) and capacitor (V c = 20V) cancel each other, making the circuit effectively resistive. Therefore, the phase difference between the applied voltage and the current is zero. For more visit here: https://www.tiwariacademy.com/ncert-soRead more

  3. The material is diamagnetic because its relative permeability (μ r = 0.5) is less than 1. For a diamagnetic material, the magnetic susceptibility (χ) is related to relative permeability by χ = μr −1. Here, χ = −0.5.

  4. The average power supplied by an AC source to a capacitor over a complete cycle is zero. This is because the current and voltage in a capacitor differ in phase by π/2, resulting in no net energy transfer.

  5. Capacitive reactance is the opposition offered by a capacitor to the flow of alternating current. It is given by the formula X c = 1/Cω, where C is the capacitance and ω is the angular frequency. Its SI unit is ohm (Ω).
