Give any two examples for a dimensional constant.

Explanation

(a) Universal gravitational constant (G)
SI unit of 'G' is ` Nm ^ 2kg ^( -2) ` and dimensional formula of 'G' is ` ( M^( -1) L ^( 3) T^ ( -2)) `
(b) Universal gas constant (R )
SI unit of 'R' is J mole `""^( -1) K^( -1) ` and dimensional formula is `( M ^ ( 1 ) L ^2 T ^( -2) theta ^( -1) mol e^( -1) ) `
