We assume the earth to be a homogeneous sphere. Let ρ be the mean density of the earth and a body be lying on the surface of the Earth, where the value of the acceleration due to gravity is g. Now, the body be taken to a depth d below the free surface of the

Let a body of mass m lying on the surface of the earth of mass M and radius R. As we know that acceleration due to gravity at the surface of the earth Let the body is taken to a height h above the surface of the Earth where the value of the acceleration due

The force of gravity acting on a body having unit mass placed on or near the surface of the Earth is known as acceleration due to gravity. Let the earth to be a sphere of radius R and uniform density ρ, then mass will be Mass = Volume ×Density If point mass m is situated
The value of the gravitational constant G was first determine experimentally by English scientist Henry Cavendish in 1798. Two small lead spheres of mass m each are connected to the end of a rod of length L which is suspended from its midpoint by a fine quartz fibre, forming a torsion balance. Two large lead
According to the principal of superposition, the gravitational force between two masses acts independently and uninfluenced by the presence of other bodies. Hence, the resultant gravitational force acting on a particle due to a number of masses is the vector sum of the gravitational forces exerted by the individual masses on the given particle. The
Let we consider two bodies A and B of masses m₁ and m₂ and separated by a distance r. Thus, vector form of the law of gravitation implies that the gravitational force acting between two particle form action and reaction pair. As F₁₂ and F₂₁ are directed towards the center of the two particles, so
The National Testing Agency(NTA) has successfully conducted the JEE Main 2023 Exam in two sessions, with Session 1 taking place in January 2023 and Session 2 in April 2023. Results for both sessions have already been released. Now, Candidates who have cleared the JEE Main 2023 exam are now eligible to apply for admissions to
This law state that ”Every body in this universe attracts each other with a force whose magnitude is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres. This force acts along the line joining the centres of two bodies. Let two bodies of masses
