Dimensional Formula for Gravitational Constant: FAQs
What is Universal Gravitational Constant?
According to Newton’s Law, the force of gravitational attraction is the force that is dependent on the masses of both bodies and is inversely proportional to the square of the distance that separates the center of the bodies. The constant proportionality present in Newton’s equation of gravitational force is called the universal gravitational constant.
What is SI Unit of Gravitational Constant?
The SI unit of gravitational constant (G) is Nm3 kg-2
What is Value of Gravitational Constant?
The value of Universal gravitational constant is given by 6.6743 × 10-11 m3 kg-1 s-2
What is Dimensional Formula of Gravitational Constant?
The dimensional formula of the gravitational constant is M-1 L3 T -2
What is Formula for Gravitational Constant?
The formula of Gravitational Constant (G) = F × r2 × (m1m2)-1
Why is G called Universal Constant?
The value of G does not depend on the nature and size of the bodies and remains same in the whole universe, therefore it is known as Universal constant.
What is Dimension of F= GMmR2?
F= GMmR2 represents the Universal gravitational constant whose dimension is M-1 L3 T -2 .
What are the Dimensional Formula of small g?
The unit of ‘g’ is m/s2 and so its dimensional formula is M0L1T-2.
Dimension of Gravitational Constant
Dimensional Formula for Gravitational Constant is [M-1 L3 T-2]. The Gravitational Constant is represented by ‘G‘. It is Newton’s gravitational constant and gives the constant of proportionality in Newton’s Universal law of gravitation which is the basis of our understanding of non-relativistic gravity.
In this article, we will discuss the ‘Gravitational Constant,’ its unit, dimensional formula, and the derivation of the Gravitational Constant.
