3. कालीबंगा (राजस्थान, भारत): यह सिंधु घाटी सभ्यता का एक महत्वपूर्ण शहर था, जो अपनी विशिष्ट ‘काली मिट्टी’ और ‘हड़प्पा संस्कृति’ और ‘पूर्व-हड़प्पा संस्कृति’ के मिश्रण वाली विशेषताओं के लिए जाना जाता है।
4. लोथल (गुजरात, भारत): यह सिंधु घाटी सभ्यता का एक बंदरगाह शहर था, जहाँ ‘डॉकयार्ड’, ‘गोदाम’ और ‘पक्की ईंटों से बनी इमारतें’ मिली हैं।
If the density of earth is doubled keeping its radius constant, then acceleration due to gravity g is
The acceleration due to gravity is directly proportional to the density of a planet, assuming the radius remains constant. This means that if the density of a planet doubles, the value of gravity on its surface also doubles. For example, increasing a planet's density while maintaining the same sizeRead more
The acceleration due to gravity is directly proportional to the density of a planet, assuming the radius remains constant. This means that if the density of a planet doubles, the value of gravity on its surface also doubles. For example, increasing a planet’s density while maintaining the same size results in a stronger gravitational pull.
This relationship highlights how changes in a planet’s internal composition, such as an increase in mass per unit volume, can significantly impact its gravitational force. Thus, doubling the density leads to a direct doubling of the gravitational acceleration experienced on the planet’s surface.
g = 4/3πGRp i.e, g ∝ p
See lessIf density is doubled, then the value of g also gets doubled.
Acceleration due to gravity g for a body of mass m on earth’s surface is proportional (Radius of earth = R, mass of earth = M) to)
The acceleration due to gravity for a body on the Earth’s surface depends on the mass of the Earth and its radius. It is directly proportional to the Earth's mass and inversely proportional to the square of its radius. This means that as the mass of the Earth increases, the gravitational pull also iRead more
The acceleration due to gravity for a body on the Earth’s surface depends on the mass of the Earth and its radius. It is directly proportional to the Earth’s mass and inversely proportional to the square of its radius. This means that as the mass of the Earth increases, the gravitational pull also increases, making the acceleration due to gravity stronger.
Conversely, if the radius of the Earth increases while keeping its mass constant, the gravitational force weakens, reducing the acceleration due to gravity. This proportional relationship explains how Earth’s mass and size influence gravity experienced at its surface.
g = GM/R² ∴ g ∝ M/R²

The gravitational force between two objects is influenced by their masses, the distance between them, and the density of the material involved.

The gravitational force between two objects is influenced by their masses, the distance between them, and the density of the material involved. When the mass of an object is expressed in terms of its volume and density, the force becomes proportional to the fourth power of the radius, assuming the density remains constant.
This relationship indicates that as the radius of an object increases, the gravitational force grows significantly due to the radius being raised to the fourth power. This dependence on radius highlights the impact of size and density in determining the strength of gravitational interactions.
F = G (m x m)/((2 R)²) = G ((4/3 πR³p)²)/(4 R²)
