What is the dimensional formula of universal gravitational constant G?
Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
What does it mean by the value of gravitational constant is 6.67×10 11nm2 kg2?
Answered 11 months ago · Author has 2.1K answers and 619.9K answer views. It means that the force of attraction between the particles each of masses 1kg placed at a seperation of 1m is 6.67×10^-11N.
What do you understand by the statement that gravitational constant is 6.67 10 11 nm2 kg 2?
67*10-11 Nm2/kg2? It shows that the value of universal gravitational constant is equal to the force of attraction acting between any two bodies each of unit mass, whose centres are placed unit distance apart.
What is value of universal gravitational constant?

What is the value of universal gravitational constant mean?
The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm2/kg2. It is an empirical physical constant used in gravitational physics. The value of the gravitational constant is the same throughout the universe.
What is the dimension of power?

| power | [M L2 T-3] | watt |
| viscosity, dynamic | [M L-1 T-1] | pascal-second |
| viscosity, kinematic | [L2 T-1] | square meter per second |
| specific heat | [L2 Q-1 T-2] | joule per kilogram-kelvin |
What is dimensional formula and dimensional equation class 11?
Dimensional Formula is the expression which shows how and which of the base quantities represent the dimensions of a physical quantity. Dimensional Equation is an equation obtained by equating a physical quantity with its dimensional formula.
What are the uses of dimensional formula Class 11?
Dimensional equations are used :
- To check the correctness of an equation.
- To derive the relation between different physical quantities.
- To convert one system of units into another system.
What is the SI unit of gravitational constant?
SI Unit: Universal Gravitational Constant: G: Gravitational Constant is an empirical physical constant that is involved in the calculation of gravitational effects in Newton’s Law of Universal Constant. Constant at any point in this universe. G = 6.67408×10-11 Nm 2 /kg 2 [L] 3 [M]-1 [T]-2: Nm 2 /kg 2
What is G constant in physics?
It is an empirical physical constant used in gravitational physics. It is also known as Newton’s Constant. The value of the gravitational constant is the same throughout the universe. The value of G is different from g, which denotes the acceleration due to gravity.
What is the value of G in physics?
What is the value of capital G? In physics, the value of capital G (gravitational constant) was initially proposed by Newton. G = 6.67408 × 10 -11 N m 2 Kg -2 The value of gravitational constant on the moon or on mars or at any part of the universe remains unchanged making it an invariant entity.
What is the universal gas constant called?
This constant ‘R’ is called Universal gas constant. Its value remains same for all gases. where P is the pressure, V is the volume, n is the no of mole, R is gas constant and T is temperature.
