The orbital speed of a satellite at height $h$ (with $h \ll R$) above the Earth is approximately:
View solution →The orbital period of a geostationary satellite is:
View solution →The orbital speed of a satellite just above the Earth's surface is approximately:
View solution →If Earth's mass were doubled and its radius halved, the escape velocity would become $k$ times the original. Find $k$.
View solution →Escape velocity from a planet depends on:
View solution →The escape velocity from the surface of the Earth is about 11.2 km/s. If the radius of Earth were doubled (mass unchanged), the new escape velocity would be approximately:
View solution →The change in gravitational PE of a body of mass $m$ raised a small height $h$ above Earth's surface ($h \ll R$) is approximately:
View solution →The gravitational field strength $g$ at the Earth's surface in terms of Earth's mass $M$ and radius $R$ is:
View solution →By convention, the gravitational potential at infinity is taken as:
View solution →Two bodies each of mass 100 kg are placed 1 m apart. The gravitational force between them is approximately (with $G = 6.67 \times 10^{-11}$ N·m²/kg²):
View solution →The SI units of the universal gravitational constant $G$ are:
View solution →The gravitational force between two masses is $F$. If the distance between them is doubled, the force becomes:
View solution →If Earth's period is 1 year at 1 AU, a planet orbiting the Sun at 4 AU has a period of:
View solution →Kepler's third law: the square of the orbital period $T$ is proportional to:
View solution →Kepler's first law states that the planets move in:
