Question

value and SI unit of capital G

Answer 1

G in physics is Universal Gravitational constant.

It's SI unit is $Nm kg^{-2}$

It's value is $6.67 × 10^{-11} Nmkg^{-2}$

Answer 2

Value of G is about 6.67408 ×10−11 SI unit of G is m3 kg-1 s-2 or N*m2/kg2

•G refers to gravitational constant.

•It is used in calculation of gravitational force.

•Law of universal gravitation stated by Newton is "that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers."

•Formula for force of gravitation -

F = G*M1*M2/r²

F is gravitational force between two bodies

R is distance between the two objects

M1 is mass of first object

M2 is mass of second object

G is gravitational constant
